  • mboisso Maxime Boissonneault (@mboisso) reported

    1/2 @SlackHQ has issues today... discussion from a Slack team: X: I keep getting Threads bolded, but it only shows me a nine-day-old thread. Still working better than MS Teams on its best day! Y: Teams works so great on Linux that MS is killing the desktop app.

  • ConnorAltDelete Connor Murphy (@ConnorAltDelete) reported

    Threads being broken in @SlackHQ is what's finally going to push me over the edge...

  • ChereneAubert Cherene (@ChereneAubert) reported

    @AlexaKilroy I just keep clicking. And clicking. It’s driving me insane. I’ve restarted. I’ve logged out and logged back in. @SlackHQ HELP US

  • jer979 Jer979.xrd ∛ (@jer979) reported

    @SlackHQ threads not appearing for me on desktop or mobile. Known issue?

  • webtwozero Alex McRoberts 👻 (@webtwozero) reported from North Vancouver, British Columbia

    @SlackHQ seeing a problem where the Threads view isn’t loading - the loading icon is just … loading for a long time

  • FreightPOP FreightPOP (@FreightPOP) reported

    @virtudeskcom @SlackHQ @Zoom They can't necessarily be used offline, but if you are having internet issues, you can use your cellular data on your phone to make video/voice calls or send out messages to team members. Super helpful in a pinch! #USAMfgHour

  • AbrahamMarin Abraham Marín-Pérez (@AbrahamMarin) reported

    @subcide @SlackHQ Oh, that’s too bad. I used to prefer zoom A LOT but that may change if they fix these issues. These new huddles are promising.

  • Alemari32284308 Alemari (@Alemari32284308) reported

    @gepeto42 @SlackHQ Slack threads not working for me

  • arturot Arturo Toledo (@arturot) reported

    @SlackHQ is down.

  • WikkidEdd Edd Smith (@WikkidEdd) reported

    @SlackHQ @apaprocki I get the same issue, but you don't even need to delete anything. Pressing backspace once doesn't delete anything, but stops the text from being a link

  • wiz0floyd wiz0floyd (@wiz0floyd) reported

    @SlackHQ We are seeing Events being sent multiple times for messages sent in a thread. I see the open issue for threads, but I want to make sure this behavior is documented too.

  • daveyheuser Davey Heuser (@daveyheuser) reported

    Slack threads aren’t showing new content despite indicating that there’s new activity. Anyone else having a similar issue? // @SlackHQ

  • cshbell Christian Bell 🇺🇦 (@cshbell) reported

    Turns out a @SlackHQ outage that prevents unfollowing a thread and its push notifications is a very elaborate form of torture.

  • JessGrossman Jessica Grossman (@JessGrossman) reported

    Yooo @SlackHQ! @blairbeckwith & I discovered a fatal flaw between our shared workspaces - we can't see each other's status updates! How are we supposed to know when someone is OOO, or in a meeting if we can't see them? Please fix so we don't seem like jerks for not responding! 🙏

  • kv_karthik Karthik (@kv_karthik) reported

    How do folks at @SlackHQ communicate with each other when there's an outage? 🧐

  • rsousamarques rsousamarques.eth (@rsousamarques) reported

    Nice... @SlackHQ is down. 👏🏼

  • brianfagioli Brian Fagioli (@brianfagioli) reported

    Omg @SlackHQ plz fix threads. You are ruining my day.

  • johnnyzhoujz Johnny Zhou (@johnnyzhoujz) reported from Manhattan, New York

    Stop slacking off and fix threads, @SlackHQ. I still love you though.

  • EuphoniaXu Euphonia Xu (@EuphoniaXu) reported

    @SlackHQ fix your threads bug please. It's been months. phantom notification on the phone app first, now on the desktop app.

  • audr3x audge (@audr3x) reported

    .@SlackHQ fix your ****

  • subcide Steve Dennis (@subcide) reported

    @AbrahamMarin @SlackHQ That's neat, people here keep having issues with permissions though that take so long to resolve that any benefit of 'quick call?' is lost and we just start a zoom.

  • adrianmg Adrián Mato 🐙 (@adrianmg) reported

    The “Threads” tab on @SlackHQ is not working for me. I just realized I couldn’t use the product without that single feature 🤔

  • aamirislam99 Aamir Slam (@aamirislam99) reported

    @SlackHQ @IanVaughan Is there a timeline on the fix?

  • janrezab Jan Rezab (@janrezab) reported

    @SlackHQ please fix downloading of files via the Mac app. Its very annoying every download gets stuck and I have to go use the web version, please...
