  • RealGeneKim Gene Kim (@RealGeneKim) reported

    @mattberan @SlackHQ I’m “glad” it’s not just me! (I’m hoping that this is a legit bug, not a transition to what someone thinks user autocomplete should be!) Oh, and also had issue where on iOS/iPadOS, user pictures were swapped around!

  • amfonte Anthony (@amfonte) reported

    @SlackHQ While you’re here, how do I get notifications across devices to sync? My issue is: 1. I close the desktop app with unread DMs 2. Notification appears on mobile devices (I leave unread) 3. I come back to the desktop app and read the unread DMs 4. Notification persists on mobile

  • dialtone_ Valentino Volonghi (@dialtone_) reported

    .@SlackHQ Hey, the emoji replacement that puts the caret before the punctuation after it is still a problem months later, but now page up/down don’t work when focus is in the input textbox. Please fix these.

  • stevemz Steve Mz (@stevemz) reported

    @leifdreizler @SlackHQ same. I have to go off wifi, force quit and then reopen to fix it.

  • KostjaPalovic Kostja Palović Appliku.com (@KostjaPalovic) reported

    @transitionswpz @discord @SlackHQ yeah discord being down sucks. where do i share my memes

  • mpt45 Kris Venden (@mpt45) reported

    Hey @SlackHQ while your new sort by recent works great in iOS, is it broken on the iPad? I got the update both places but my iPad does not show the same menu to choose most recent like the iPhone does. I’ve hard closed the app many times..

  • WillGregorian Will Gregorian (@WillGregorian) reported

    I'd love it if @SlackHQ let me lock a thread. Sometimes, I just want to shut it down.

  • KaraRyli Kara Cannon (@KaraRyli) reported

    My @SlackHQ muted channels moved all the way down below my (dozens of) direct messages, making them hard to get to. Is there any way to get them back with the other channels?

  • D_creatiVe Dominique Williams (@D_creatiVe) reported

    @SlackHQ my sections at all gone and when I try to recreate them it says they are already made, help?!

  • brettg98 brettg98 (@brettg98) reported

    @RealGeneKim @SlackHQ Yep. Also having the same issue. Heh.

  • dviate Jermaine (@dviate) reported

    @marsbergen @SlackHQ Which version? In 4.23.0 still the same issue…

  • SquidDLane Ryan Lane (@SquidDLane) reported

    @SlackHQ you really need to fix this, because it's simply broken.

  • marcelhadorn M (@marcelhadorn) reported

    Customer service of Slack is formidable and definitely one of the main reasons we at @DuotonesLLC won't even consider looking at any of their competitors. Most (tech) companies could learn a lot from customer satisfaction efforts of @SlackHQ! #CustomerExperience

  • TwistedEdge James Baldwin (@TwistedEdge) reported

    Is @SlackHQ just super slow for me or is anyone else experiencing issues?

  • SoopTikoon Soop Tikoon (@SoopTikoon) reported

    @SlackHQ I still miss glitch

  • RenanAZ Renan AZ (@RenanAZ) reported

    @SlackHQ I need my Melting emoji kinda urgently Slack - help me out here

  • mr_modular Allen Nemo (@mr_modular) reported

    Holy moly, my @SlackHQ for Windows 10 was so terrible and laggy, I couldn't even scroll up and down my list of rooms without multisecond lag. Yet Mac App? Fine. Both 16GB up-to-date machines (Dell i7/Mac M1)

  • mattrw89 Matt Webb (@mattrw89) reported

    3. With 2 CSRs the main thing to juggle is follow-up calls. Has this person been called back? Parts get ordered? Not dropping ***** between them is key! We setup @SlackHQ in Phase 1 for int. comm. and piped in almost every email/answering service/online booking -> Slack chans.

  • rahul_ramfort Rahul (@rahul_ramfort) reported

    @_swanand @SlackHQ How does this help though? Isn't custom sections better way to organise channels and DMs?🤔

  • marsbergen Patrick van Marsbergen (@marsbergen) reported

    @SlackHQ The issue seems fixed! cc: @dviate

  • bajicdusko Dusko (@bajicdusko) reported

    @ArnautovicAmmar @iamchataa @SlackHQ Yup, I kinda accepted that. We're kinda still small enough to not to write down these procedures on paper. I'm most probably wrong about it. On the other hand I don't wanna be a "process tsar" (I tend to be 🤫)

  • andrhamm Andrew Hammond 🤘🏻 VACCINATED! (@andrhamm) reported

    @linear @Jira @SlackHQ Specifically link unfurling and ways to quickly draft todo list items or issues from a given Slack message / thread

  • me1000 Randy Luecke🤦🏼‍♂️ (@me1000) reported

    @SlackHQ That didn’t fix it. I’m still getting badges on my iPhone app. This has been pretty consistently broken for months. Badges clear when I open the app/workspace. Then sometime later it comes back.

  • MoDrakM Mike MoDrak (@MoDrakM) reported

    @SlackHQ much needed feature: the ability to push/drag n drop/move thread replies into the thread. My slack channels are often as messy, if not worse than my inbox. People just don’t use threads. Or have AI that suggests replies as thread replies. Please look into this CX issue!

  • TarunMangukiya Tarun Mangukiya (tarunm.eth) (@TarunMangukiya) reported

    Alexa Ranks are shutting down and it feels like an end of an era. I think it has been an important metric for lot of startups and products. When we started @Iconscout back in 2016, we created a @SlackHQ channel named #alexa-rank-global and #alexa-rank-india.

  • ChrisHantis Chris Hantis (@ChrisHantis) reported

    @lexfridman Let’s cut it down even more - 1 @SlackHQ message.

  • samsm Sam Schenkman-Moore (@samsm) reported

    Feature request: Cool down on Slackbot custom responses so that you don't get the canned response over and over and over in a channel cc @SlackHQ

  • gregtitus Greg Titus (@gregtitus) reported

    @jeffwatkins @SlackHQ I'm having the same bug. It shows up when you have any unread channels. It looks intended to be for if you have to scroll down to unreads, but it sits there at the bottom even when my channel list isn't scrollable and I can see all of them.

  • AmitKarr Amit Karr (@AmitKarr) reported

    @SlackHQ there seems to be an issue with the slack integration in Outlook for MacOS.

  • Ocramius `replaces: *` (@Ocramius) reported

    If I reduce my CPU cores to 2 (down from 8), then @SlackHQ no longer loads in under 3 minutes. How did we end up with such uselessly bloated software? 😩
