  • yohannp Yohann Prigent (@yohannp) reported

    @SlackHQ Hey, this bug is now 1.5 years old, congratulations!! More seriously @SlackHQ it’s such a shame you don’t fix this bug breaking all french messages with lists embedded.

  • akash_nu 🖥 Akash 📱 (@akash_nu) reported

    @SlackHQ And not just that, it also crashes on iOS randomly when I try to tag people. Is there any known issues around this? It’s been going on for some time now.

  • HDiacono Helen Diacono (@HDiacono) reported

    Hey @SlackHQ I updated my mac to Catalina 10.15.7 and now Slack won't open. Any chance of a fix?

  • epytwen Macky Tanaka (@epytwen) reported

    First world problem: In @SlackHQ how to get everyone to start using threads instead of writing directly to the channel? Or is the thread feature bad? I wish I could just drag and drop people's comment and sort them into a thread lol

  • avaolon AvalonStar (@avaolon) reported

    @SlackHQ your service is not sending the login code emails when trying to log into a new computer.

  • jasonkneen Jason Kneen (@jasonkneen) reported from Ludgershall, England

    Jesus @SlackHQ your sign in process is a mess — dealing with multiple devices is ridiculous. If I’ve signed up on an iphone with biometric security, why on EARTH does the desktop app not just sign in automatically? Your UX is just terrible.

  • iainmspillane Iain pays for his comics (@iainmspillane) reported

    Getting some annoying crashes and ‘issues’ with the @SlackHQ iPhone app. 😠

  • mrtrash757 Ross (@mrtrash757) reported

    @asksalesforce @Benioff I guess so. But 5 year issues... come on. Maybe when the dust settles on the @SlackHQ acquisition, Salesforce can finally invest into it's product and development teams.

  • iamsmkr Shivam Kapoor (@iamsmkr) reported

    @SlackHQ Please fix your Andriod app notifications at high priority! It is a serious bug.

  • ryanmckeen Ryan McKeen (@ryanmckeen) reported

    I’m digging @SlackHQ ‘s huddle feature. It solves a problem that I didn’t know that I had - namely the friction from going from slack to quick call.

  • PhotoAmy33 Amy Kaplan (@PhotoAmy33) reported from Costa Mesa, California

    Is @SlackHQ down for anyone else or is it just my ****** free airport wifi?

  • CuriousRoberto Roberto Oliveira (@CuriousRoberto) reported

    I just learned that @SlackHQ was originally a game (called Glitch) which was on the verge of being deactivated.

  • codykonior Cody Konior (@codykonior) reported

    @SlackHQ I think you've broken your "Email" plugin in the past 24 hours. HTML emails with <pre> tags are now having the newlines stripped from the bodies, where yesterday (and the past few years) they weren't.

  • mengopoo Mengopoo (@mengopoo) reported

    hey @SlackHQ, names are showing blank on your desktop app. I can't see who I'm speaking to in the app. Clearing cache didn't help.

  • RenatoVrolijk 1R8200 (@RenatoVrolijk) reported

    Hate it ora Slack ta glitch... Get your **** together @SlackHQ

  • Redhead4America Marleneusaa1 (@Redhead4America) reported

    @SlackHQ I want my tweets to go to my mail as before. This notification is terrible.

  • _changxu Chang Xu (@_changxu) reported

    Why is @SlackHQ so bad at keeping multiple devices in-sync? Is anybody solving this problem?

  • masturbator1138 Masturbator1138 (@masturbator1138) reported

    @SlackHQ What's a channel? It's a place where all the wrong people, irrelevant messages, and out-of-date files pile up so you can't get anything done. Your problem won't get fixed in a channel. Only an Indian guy with a name you can't pronounce can fix it...and he's off work until Monday.

  • jmargey jmargey (@jmargey) reported

    @sarahdoody @SlackHQ OMG, Duh, user error by me, you can actually scroll the page to see the audio settings for notifications. 😔

  • Bitonaut Bitonaut (@Bitonaut) reported

    @SlackHQ Yes. I try to upload a file in a conversation or channel and then I or someone else tries to download that file. When trying that I only get back a text file with an error. Upload does not work on the Slack Mac app and Web. Download does not work on slack on Mac, web and ios.

  • kebabmaihaddi Aviral Srivastava (@kebabmaihaddi) reported

    @SlackHQ , having this issue with notifications/unread. The Threads section always show as 1 unread message but all are read. Had this issue in Mobile after update and now on my Mac too.

  • SupahNava Chani Nava (@SupahNava) reported

    @SlackHQ @sreecharan93 Just found this thread while looking up how to fix this issue. The current system of tying hair color and skin color together is REALLY not a good look, Slack, and DEFINITELY should be fixed by now, you know, almost three full years later.

  • katiedoesseo Katie (she/her) (@katiedoesseo) reported

    @howdydoughty @SlackHQ @blakedenman Have him check what source his microphone is coming from DURING a call. I had this happen to me and I had to have someone call me, NOT hang up when they realized what was going on, and let me fiddle with the sound options directly within the call screen to fix it.

  • envygeeks Jordon Bedwell (@envygeeks) reported

    I wish @SlackHQ would fix their badge gaslighting issue. You know the issue where they say I have one new message but I don’t

  • johnfhook John Hook (@johnfhook) reported

    I am now a single-issue voter with that issue being that It Should Be Illegal For @SlackHQ To Use The @SlackHQ Sound In @SlackHQ Commercials

  • istrakhov Ivan (@istrakhov) reported

    @SlackHQ When will the fix be released?

  • phillijw Joe Philwaukee (@phillijw) reported

    @SlackHQ FYI, when slack is down (like now), the browser tabs chew through CPU and bog my machine down

  • thetombell Tom (@thetombell) reported

    @SlackHQ the "Turn off notifications for replies" on threads has broken for me again, I turn it off, then I still get notified about replies still

  • howdydoughty Kim Doughty (@howdydoughty) reported

    Hey @SlackHQ, we've been experiencing an issue where I can't hear @blakedenman when we're in Huddles. It was working just fine two days ago. We've double checked that mute was off. Any ideas for a fix?

  • sapient_digital Giles W. Crouch (@sapient_digital) reported

    The problem with @SlackHQ is they don’t understand digital culture so are only worth $25B & @basecamp does so they’re worth $100B with less churn & more loyalty & happiness. #SaaS
