    @SlackHQ How was this video made? Can someone help with the tool that was used to create this video?

  • AnthonyKinson Anthony 🇬🇧 (@AnthonyKinson) reported

    Hmm, closing or commenting on @github issues now posts in @SlackHQ that the issue was created, in addition to the actual action. That's going to get really annoying really quickly. Hope this is a bug and not a feature... something updated somewhere...

  • jenlampton Jen Lampton 🐱💻 🐎⭐ (@jenlampton) reported

    @SlackHQ That's terrible! Are there plans in the works to fix that any time soon?

  • andupotorac Andu 🇺🇦 (@andupotorac) reported

    @DominikTo @SlackHQ How would that help Slack?

  • justbhutani Bhutani (@justbhutani) reported

    @SlackHQ your ios and Mac app are consistently **** , so buggy - unreads is broken updates don't work

  • matt_muffin Matt Greenberg (@matt_muffin) reported

    @SlackHQ mobile app has been becoming less and less reliable. Showing notifications but not the message, dropping messages in channels, and failing to send without errors. If you wanna replace email it needs to work 💯

  • pixelpartner Thomas Kumlehn (@pixelpartner) reported

    @SlackHQ Fix it first in the backend

  • mickteran mickteran (@mickteran) reported

    @SlackHQ hi there, my Threads section remains bold although there are no new replies. It happens in both the Mac OS and iOS apps. How can I fix it?

  • scottymomo Scott M (@scottymomo) reported

    @xsimxphoto @SlackHQ Driving me nuts too.. finally got it to go away after trial and error using your suggestion

  • pixelpartner Thomas Kumlehn (@pixelpartner) reported

    @SlackHQ auth via 6-letter-code seem broken, please check

  • darraghs Darragh Sherwin (@darraghs) reported

    Dear @MicrosoftTeams if I’m going to have to switch from @SlackHQ. please fix teams to have more than one organisation, it sucks having to sign in and out

  • witt_Traxie Whitney Tracy (@witt_Traxie) reported

    @SlackHQ @encthenet hello, got a problem with 2 FA, how could i process to log in my account (cuz it says my password is wrong)

  • RedSlingerNYC Sean Wyngaard 🇺🇸🇿🇦 (@RedSlingerNYC) reported

    @SlackHQ Hi.. I swapped out monitors on my Windows 11 PC, and since then, I can't get sounds on my Action Center notifications. Please help.. :(

  • squeal Karan Saini (@squeal) reported

    @epicpewpew @SlackHQ if it uses some stored token that refreshes every time a new session starts, possible that the message is due to it being malformed due to some outage (?) v interesting… or maybe 2FA set-up deadline kicked in

  • jmbrkphd jmb, phd (@jmbrkphd) reported

    Is it just me, or does @SlackHQ have a terrible implementation of threads? Wish I could turn it off, or force it to show in the main posts to the channel by by default. I’m constantly missing replies buried in threads. #slack

  • SimpleSimpleAds Simple Simple (@SimpleSimpleAds) reported

    @SlackHQ / your customer support chat hasn't been able to solve our problem for over three months! it's really frustrating. is there someone we can talk to? chat isn't working.

  • blackgik blackgik.eth👓 (@blackgik) reported

    is @SlackHQ down?

  • mrlopis Joao L. (@mrlopis) reported

    @SlackHQ hey, can you please pay a bit more attention to your Firefox users? I know you don't care much and ignore us for years, but at least keep the web app minimally functional if possible. There's hundreds of error on the console, most navigation is broken.

  • spoo4 Wolf (@spoo4) reported

    @CubicleApril @gavinsharp @SlackHQ My work machine is a Macbook Pro running Monterey, using the slack app (rather than the website). Never have a problem with it messing up my code when I use the three backticks. I'm sorry this must be frustrating as ****

  • hellomrdavis Eric Davis (@hellomrdavis) reported

    @SlackHQ Looks like the issue resolved itself with a restart. All good now.

  • justkelly_ok KILL-y Ellis 🔪 (@justkelly_ok) reported

    @BigTechAlert @stewart @SlackHQ I just reactivated, calm down bots

  • littlewolfbird LittleWolfBird (@littlewolfbird) reported

    @SlackHQ I would really like to talk to a human about an issue I’m having. Your “help center” is not helping. Where can I do that?

  • paulienuh Pauline P. Narvas ⭐️ (@paulienuh) reported

    @_nancychauhan @SlackHQ Slack, fix this

  • toddnel1021 Todd Nelson (@toddnel1021) reported

    @SlackHQ Just so you know the issue is once you have used the app, the moment you log into the browser view, it opens the app. It’s nearly impossible to get the browser to not open the app.

  • deanw83 Dean Welbourn (@deanw83) reported

    @xsimxphoto @SlackHQ Still broken for me this morning!

  • jamespresc James Prescott 🇺🇦 (@jamespresc) reported

    @SlackHQ why have you disabled the ability to share .patch files over Slack? They're basically just text files and being forced to zip and unzip them is just slowing my collaboration down 😔

  • jmbrkphd jmb, phd (@jmbrkphd) reported

    Is it just me, or does @SlackHQ have a terrible implementation of threads? Wish I could turn it off, or force replies to also show in the channel by default. I’m constantly missing replies buried in threads. If you want to keep a secret, post it as a threaded reply in #slack.

  • suhas_rd Suhas Deshpande (@suhas_rd) reported

    @SlackHQ, we at @trycourier are trying to understand what exactly you mean by the error `msg_too_long`. docs are not making it super clear at what level you apply the limitations

  • mrlopis Joao L. (@mrlopis) reported

    @SlackHQ There were tons of networks errors in the console. The only thing that worked was opening slack in a new firefox container. I tried firefox in troubleshoot mode (no extensions), i tried deleting every cookie and localstorage i could find, logged in again, nothing.

  • SeanBre90802616 Sean Brennan (@SeanBre90802616) reported

    @SlackHQ i guess there was glitch going into slack ?
