  • larsboehnke Lars Böhnke 🚀 (@larsboehnke) reported

    @SlackHQ the macOS app isn't loading but the status page says all is right. Any known issues?

  • JezebelKat Kat Callahan 🍱 (@JezebelKat) reported

    @_Desmoden Just a terrible idea from @SlackHQ. Hope they get rid of this feature.

  • rfsatar Ros Satar 🇬🇧 🇪🇺 (@rfsatar) reported

    @SlackHQ So there was a wide issue with your app and you declined to mention this? Moving everyone to Telegram.

  • STEELK1969 Kelly McPoland (@STEELK1969) reported

    @SlackHQ 100% remote work is most suitable for my effectiveness. I am much more focused, efficient and productive working at home. Boundaries are never a problem because overtime must be approved in my non exempt role. I stick to my schedule and address new business the next day.

  • anahnarciso Ana Henriques Narciso (@anahnarciso) reported

    @SlackHQ Thank you for your reply! No, I definitely did not press that combination. But just before that I noticed erratic behavior while trying to edit messages. I believe you had a bit of an outage, right? Could you have reset messages to flush some servers?

  • futene_cat 不貞寝 (@futene_cat) reported

    @SlackHQ Hi, Since I have changed Macbook(M1) I can't receive any notification from Slack. and also I can't see Slack icon in system preference on macbook. my college is facing same problem. Could you support?

  • aganglada Alejandro [...👨🏻‍💻] (@aganglada) reported

    And now, @SlackHQ is not working... what next

  • mkgedades Kenneth Edades RN (@mkgedades) reported

    @SlackHQ Is your system down coz I can’t open my desktop app and mobile app.

  • GisseleBautista Gissele Bautista (@GisseleBautista) reported

    Yo @SlackHQ are you down??? 😓

  • RobinVerl Robin Verlangen (@RobinVerl) reported

    @SlackHQ having issues? get push notifications but most channels not loading #NLD

  • Matt_Daniel_ Matt (@Matt_Daniel_) reported

    @SlackHQ Are you embracing the future? In 1989 they thought we would have been mass producing flying vehicles for folks by the year 2015. Not only hasn't mass production of flying cars happened but we aren't even close. We are much closer to drones doing a delivery service.

  • anildash Anil Dash (@anildash) reported

    @davidgsIoT @SlackHQ I think the fact that you have to approve a connection before they can send you a message should help mitigate those issues a lot.

  • MaggotMouth Willem Potgieter (@MaggotMouth) reported

    @SlackHQ Are you aware of any problems with regards to threads on desktop app atm? I'm getting notifications for new messages on existing threads, but the thread indicator (and all unreads) on the sidebar stays unlit (not the case for new threads)

  • clinejj John Cline (@clinejj) reported

    @SlackHQ Thanks for sharing. I think the ability to block DMs from unverified organizations could help reduce spam, but since you aren't accepting verification requests this makes that functionality much less useful

  • futene_cat 不貞寝 (@futene_cat) reported

    @SlackHQ Hi, I haven't been able to receive any notification from Slack since I have changed Macbook(M1) . and also I can't see Slack icon in system preference on macbook. my co-worker is facing same problem. Could you support?

  • j_duffy01 James Duffy (@j_duffy01) reported

    @Jaywalker @SlackHQ I guess what i’m trying to say is something that’s sufficient for one organisation might not be for another. On paper something might look okay, but in practise there could be a different impact when considering service usability.

  • rfsatar Ros Satar 🇬🇧 🇪🇺 (@rfsatar) reported

    God help us if @SlackHQ is the 'future' of remote working as @BBCNews is reporting. After yesterday's issues I am looking to move the team to @TelegramSupport

  • mint_tamas tamas (@mint_tamas) reported

    @SlackHQ @freillamae13 you status page shows no error but slack doesn't even load now. It says "Service unavailable".

  • kenstering Kenster C (@kenstering) reported

    @enjoyGLOBE i cant access @SlackHQ please fix

  • Patty40641144 DrainTheSwamp2022 (@Patty40641144) reported

    @SlackHQ Your town needs to learn from Biden. By announcing in advance through city's border will send it Flux of new residents. Better put resident requirement in place otherwise the reparation pol of money will be watered down and long time residents will get less .

  • AshMcConnell Ash McConnell (@AshMcConnell) reported

    Looks like the @SlackHQ API is down?

  • Matt_Daniel_ Matt (@Matt_Daniel_) reported

    @SlackHQ In the future people wont have to trouble themselves with moving. EVERYTHING will be brought to them. Everything. This is DE-livery which is the opposite of Livery Services.

  • antukingtrash 🪐 (@antukingtrash) reported

    Hey @SlackHQ u down?

  • dylanjwhite D J W 🎈 (@dylanjwhite) reported

    @SlackHQ I'm seeing an issue where reactions are auto-sorted if their name contains only numbers. :bug: :100: #reacji #emoji #slack

  • gnumoksha cat /dev/urandom (@gnumoksha) reported

    @SlackHQ But there are other issues too: - Read messages on computer didn't stop slack mobile to show the notifications (this is way I've turned off mobile notifications) - On a channel, read a message that was also sent to a thread didn't stop "Threads" section to be in an active state

  • anahnarciso Ana Henriques Narciso (@anahnarciso) reported

    @SlackHQ Thanks, so I should send you an email describing the whole issue and pointing to this thread?

  • MarkSussman_ Mark Sussman (@MarkSussman_) reported

    @SlackHQ This is been a longstanding issue where Android push notifications across multiple phones (including my current Pixel 5) where push notifications either are severely delayed or never come through at all. This is a regular and consistent issue (yet random)

  • k_eichinger Kai Eichinger (@k_eichinger) reported

    So with @SlackHQ being down (or having a lot of issues): Is it too early to call weekend?

  • sammielee46 S L Thomas Author (@sammielee46) reported

    @SlackHQ hey team 👋🏼 I keep getting kicked out of Slack mobile (it’s up to date, and I’m using an iPhone 11). #help

  • villares Alexandre B A Villares☂ (@villares) reported

    @SlackHQ nah! sorry for venting my anger. I'll delete the tweet soon. I after much trial and error I found the correct email/workspace combination :(
