Slack Issues Reports

Latest outage, problems and issue reports in social media:

  • SamGreenwoodTNS Sam Greenwood @🏡 (@SamGreenwoodTNS) reported from Vaughan, Ontario

    @SlackHQ I'm having issues with Slack for Windows using absurd amounts of CPU. It generally uses between 8% and 20% if my computers CPU.

  • bastilian Sebastian Gräßl (@bastilian) reported

    Dear @SlackHQ, "threads" are great, they help have a focused discussion. But, threads in Slack are the worst. Here are my suggestions to fix them:

  • snim2 Sarah Mount (@snim2) reported

    @SlackHQ That's an interesting thought. I actually wasn't in full screen, but toggling between those modes doesn't reveal the menu bar, so I can't select the Window drop-down. Thinking about it, this seems more likely to be a window manager bug?

  • flowdee flowdee ツ (@flowdee) reported

    @TacoVerdo @SlackHQ Indeed, that's a big problem, when software companies just don't share a proper changelog. I also don't like when they just show an external URL which forces me to leave the current environment just because they are too lazy :)

  • JacquelynGill Dr. Jacquelyn Gill (@JacquelynGill) reported

    @SlackHQ I'm noticing a problem where I upload a file and it disappears once it's uploaded (without posting to the channel). Hitting submit during the upload doesn't seem to prevent this. Any ideas?

  • jribbens Jon Ribbens (@jribbens) reported

    @SlackHQ I'm trying to create a channel in our Slack workspace, it says "That name is already taken by a channel, username or user group". The name is not, in fact, taken by a channel, username or user group. How do I fix this please?

  • SamanthaZeitlin Dr. Samantha Zeitlin (@SamanthaZeitlin) reported

    @adammckerlie @SlackHQ Are they having an outage today? I tried to upload an attachment earlier and that feature seems to be broken right now...

  • noahlz noahlz (@noahlz) reported

    @johnnyrodgersis @SlackHQ When are you re-launching Glitch tho

  • aafaq_gp Aafaq Ahmad (@aafaq_gp) reported

    Hi @SlackHQ few of my contact names and avatars are hidden, just saying "private user info" on hover. This is happening only on chrome browser, safari works fine. Any fix for this?

  • haydenalcalde Hayden Simmons (@haydenalcalde) reported

    moral of the story: @SlackHQ, please fix your pricing for communities!

  • rbutlerUK Rob Butler (@rbutlerUK) reported

    @SlackHQ - our trial ended & back to standard, Slack won't show any of my channels or DMs unless I use search to find them. Although they exists, the channels are not showing on the sidebar at all.... no amount of reinstalling, signing in/out has fixed! Please help...

  • JeffreyHPierson Jeff Pierson (@JeffreyHPierson) reported

    @SlackHQ @robertfriberg Would Slack see any value of baking in a feature which would suggest moving certain threads or messages to different channels depending on the topic and content? Having this work for DMs could also help to keep communication in the correct place.

  • jaywillis Jay Willis (@jaywillis) reported

    Hi @SlackHQ I found an egregious design flaw, on the mobile app every DM has a button in the upper right corner where so much as grazing it immediately starts a video call with EVERYONE IN THE THREAD please fix this oversight immediately

  • Morriz Morriz (@Morriz) reported

    @slackhq I can't create a user group called "marketing" or "dev" if we have a channel by that name already? That seems unlogical, so I assume you deem that to be a technological limitation on your end. Any fix coming? #poor #ux #missedopportunity

  • kgditcham Kevin Ditcham (@kgditcham) reported

    @joshharsant @SlackHQ 😪 will take some getting used to. Slack feels like the team is constantly around. But maybe it will be good for my ‘down time’ 💪

  • tlatsipinker Motlatsi. ♌ (@tlatsipinker) reported

    @SlackHQ is down. #SOS! 😩😩😩

  • onalark Steph (Paddock||Shaver)‽ (@onalark) reported

    @HawkinsTammy @SlackHQ The Outlook integration isn’t terrible. /remind was good. And when I could get it to work the Jira broadcast to channel could be handy.

  • kevvurs a2V2aW4= (@kevvurs) reported from Seattle, Washington

    @eddydelva @SlackHQ I can't type fast enough to see this problem

  • santinialberto Alberto Santini (@santinialberto) reported

    @SlackHQ Yes, the issue is that. It is about the messages from a bot. Thanks for investigating.

  • Dymaxion Eleanor Saitta (@Dymaxion) reported

    @SlackHQ Hey, is there a way to get a slack's icon (on the far left, when you're signed in to multiple slacks) to also show a red dot for thread replies, not just DMs? It sucks to get a notification sound and then have to hunt down where it came from.

  • WolfSparrowPub Teresa ☕️ Book Cover Designer (@WolfSparrowPub) reported

    @SlackHQ Hey, I have an issue on iOS where I will send a message and then that message reappears in the text field again, even after it's been sent. Do you know what's causing this? (And this is after clearing the cache and restarting the phone.)

  • wearegrow Alasdair Inglis (@wearegrow) reported from Lambeth, England

    @SlackHQ Possibly. I took thirty minutes to update my photo as a png. Could you make this issue work for humans.....please!

  • R1CH_TL Richard Stanway (@R1CH_TL) reported

    @SlackHQ No error, the new messages just don't load and I get a permanently stuck unread notification on the channel or DM. Restarting app after force close sometimes helps, but not always. Other colleagues also report the same problem. Have a screen recording of it too if it helps.

  • robertfriberg Death by ORM (@robertfriberg) reported

    @SlackHQ The short answer is to prevent knowledge loss. I see a tendency that a lot of problem solving happens in DM's between 2 members. A bot that reminds you and asks for confirmation before sending a DM would be even better.

  • eddydelva Eddy E. del Valle (@eddydelva) reported

    The core feature in @SlackHQ is typing and is completely broken: huge delays, types in bursts, very annoying... how can you break your core feature so much like that?

  • MorganGeek Morgan 👾💬 (@MorganGeek) reported

    The world suddenly became a more dangerous place since EDIT is broken for me in @SlackHQ. Sigh...

  • MBrooksUK 💻 Michael Brooks (@MBrooksUK) reported

    @Ocramius @SlackHQ The trouble is, a lot of workplaces refuse to use it because they think it's just for gamers and game streamers. It's a huge shame because I feel Discord is such a better platform overall.

  • railfan_ Sri 🐦 (@railfan_) reported

    @SlackHQ I use Slack in the browser and every time I open a slack URL, you ask me if I want to open the Slack app and every time I have to click "open in browser". Can you fix this so it remembers my choice? I have no interest in downloading the Slack app.

  • DeviceCoders Device Coders Inc. (@DeviceCoders) reported

    @SlackHQ Seriously, this arcane login system is driving me absolutely crazy. WHY? Why do I have to remember the god damned url of a dozen project workspaces when i have these stupid things bookmarked already???? CAN YOU FIX IT!

  • coenhyde Coen Hyde (@coenhyde) reported

    I wish @SlackHQ had a "send message at .." in the recipients timezone. I hate sending messages to people in their down time knowing they may see it and think it about it, or worse action it.
