Latest outage, problems and issue reports in social media:

  • johnwbaxter John Baxter (@johnwbaxter) reported

    @SlackHQ Hey, installed the update and it still has the same problems. It doesn't seem capable of looking for new messages when you switch to the app. One amongst a few issues it has...

  • UriahBlatherwi1 Uriah Blatherwick (@UriahBlatherwi1) reported

    @SlackHQ @PatrickKlug So tired of looking at the green border. Please fix.

  • KevinManLegends MK @ FF (@KevinManLegends) reported

    All of a sudden @SlackHQ whenever I click on a channel instead of bringing me to the newest messages it brings me up as far away from it as it can go or to the beginning of the day. Super annoying, is there a fix for this?

  • HrMervin Mervin ✈ (@HrMervin) reported

    @SlackHQ notification issues have cost me dearly, numerous times and once again today. I can't squash this well enough on Windows, and it's a problem.

  • galstar Schlez (@galstar) reported

    @SlackHQ is this possible to do login with Slack without going through the hell of reviewing an app? So many steps to do for a simple proof of concept that I want to share with friends. Can it be simpler for apps that don’t need to be on the app directory?

  • Paulina65372074 Paulina (@Paulina65372074) reported

    @codebeta_cr @SlackHQ Lot's of scammers in the group, I have been scammed twice, but I was finally recommend to #joe_cyber_recovery#_ on who helped me out with my account issues...

  • Pauline_Cx Pauline C - 60/100 (@Pauline_Cx) reported

    @Al_Grigor @DataTalksClub @SlackHQ It is yes... but this UI is a problem with Slack, not your community

  • astrochunly Chun Ly, Ph.D. (@astrochunly) reported

    When clicking on links in @SlackHQ, the default should be HTTP secure. Yet, this is not happening: Simple "site-dot-com" will redirect to " Only way to avoid this is to explicitly state so. Seems like an easy fix that would increase security for many users!

  • JeffreyWhitlock Jeff Whitlock 🇺🇸 🇺🇦 (@JeffreyWhitlock) reported

    Dear @SlackHQ - Since no one besides @MicrosoftTeams can get a toehold in the market, can you please do us all a favor and fix threads? The mental load and workflow to make sure you don't lose them are exhausting.

  • sdotsen sdot (@sdotsen) reported

    @shar1z @SlackHQ Haven't had any issues with it crashing but my android shows new msgs in a thread. Like I can't get rid of the notification. There are no new messages.

  • doubledickulous GOP's Missing Moral Compass (@doubledickulous) reported

    @SlackHQ It may have been a temporary issue. It was still happening this morning after rebooting my phone, but now appears to be fine. I'll report back if the issue repeats.

  • codebeta_cr Nicole Daniella Murillo (@codebeta_cr) reported

    @SlackHQ really love it when I'm in the middle of something and Slack suddenly decides to close the session and require me to login again. Why can't it do that when I open the app and not in the middle of the day?

  • royGED ♟️ (@royGED) reported

    @SlackHQ please i want to be able to "mark as read" from my notification drop-down. this is 2022.

  • rezzxbt RezZ (@rezzxbt) reported

    @PatrickKlug @SlackHQ Still an issue, having it now

  • deulamco deulamco.tez♦️ (@deulamco) reported

    @SlackHQ I honestly think you guys should change the flow here : 1. Login the workspace I want to remove. 2. From my profile > View Preferences 3. Find the red quit option here It’s very counter-intuitive since this could have been inside workspace switching menu.

  • doubledickulous GOP's Missing Moral Compass (@doubledickulous) reported

    @SlackHQ @stewart @LindaLacina Issue with Slack on iOS where after sending a message, it acts like you're still in the middle of a message. It doesn't want to capitalize the first letter and suggested words seem like it's considering letters already sent, even though the text field is currently blank.

  • nickvalluri Nick Valluri (@nickvalluri) reported

    @SlackHQ on mobile some of my starred channels keep disappearing from view if they have unread messages. Is that a known issue of any kind? It’s hard to check them (I have to search for the channel)

  • rottendoubt Patrick Lee (@rottendoubt) reported

    @SlackHQ hmm, it's starting to slow down again. I think it has something to do with one of the recent updates, because it was fine a few months ago. 😑

  • ftp_alun Alun Jones (@ftp_alun) reported

    @johnwbaxter @SlackHQ I'm experiencing this same issue. Uninstalling @SlackHQ from my phone today. Let me know if you fix it. It's awful.

  • mquinsland mquinsland (@mquinsland) reported

    @rotnroll666 Seriously? I absolutely hate @SlackHQ . I can't believe that we use software with such a terrible UX. Finding & organizing things is awful.

  • rmdmac rmd.eth 🧠 (@rmdmac) reported

    @SlackHQ, for the second time in a row, a support agent of yours ghosted me. Can you help? 💟

  • stevekreeger Steve Kreeger (@stevekreeger) reported

    @johnwbaxter @SlackHQ I have to say I've seen a couple of these issues on mobile app (android) recently but as I don't use it as much anymore ignored them but sounds like it's an android app issue

  • JasBoyce Jason Boyce (@JasBoyce) reported

    @SlackHQ Having a heck of a time reaching anyone at Slack who can help me cancel an annoying $8 monthly charge for an external channel I closed 6 months ago. Billing support is non-existent. I should be able to easily cancel an unused channel.

  • iamsapegin Artem Sapegin (@iamsapegin) reported

    Another issue that communication apps alike @SlackHQ could help solving but decide not to is educating users how to be respectful. For example, apps allow people to send machine gun sequences of short meaningless messages that are impossible to understand until you get them all.

  • ftp_alun Alun Jones (@ftp_alun) reported

    It's gone from intermittently broken fully over to intermittently usable. Uninstalling it. I'll start contacting my colleagues in @MicrosoftTeams until @SlackHQ gets their Android **** together.

  • AngryPets Michael K. Campbell (@AngryPets) reported

    @SlackHQ , I've documented an ugly security vulnerability with Slack Connect - what's the easiest way for me to securely communicate this info to you? Documentation = ~2 min video showing the problem.

  • AppShrugs Shrugs App (@AppShrugs) reported

    @rogerluan_ @SlackHQ I don't think that an OpenSource app would help that much (I actually consider putting @AppShrugs into FOSS at some point, but TBH I don't really see how that work out well. The complexity is too big for occasional contributors).

  • casspa Cass Anderson (@casspa) reported

    @SlackHQ every time I toggle between Slack rooms it bumps me back to midnight last night and I have to scroll through the day's messages again. Happening in every room and DM. So much scrolling. No clue who to fix this

  • valyus Alex 🇺🇦 (@valyus) reported

    My biggest struggle with the @SlackHQ is that some people respond in threads and others as the following message. @MSTeamsChat surprisingly doesn't have such an issue.

  • cfdude Rob Sherman (@cfdude) reported

    @SlackHQ I literally just typed the word "your" in a sentence (on Mac) in Slack and it has a red squiggly line under it. I see issues like this with spellcheck everyday. I'm on a new mac and new version of Slack.. same problems.
