Latest outage, problems and issue reports in social media:

  • Verbal_Pugilist The Philanthropic Charlatan. (@Verbal_Pugilist) reported

    Fix your ******* mobile notification settings @SlackHQ.

  • ObsidianDev Fergal Reilly (@ObsidianDev) reported

    @SlackHQ got 2 issues on iOS (14.6). App Version 21.06.20) 1. There’s almost always one channel that refuses to come off unread, no matter how many times I go into it. Different channel every time. This is pretty recent.

  • kall Karl Sander (@kall) reported

    @vavroom @SlackHQ honest question: why is that a problem? I hate the twee style but I don‘t see why it should mention a11y. If you need the feature, you know you need it.

  • phalanges dr. amanda pogue (@phalanges) reported

    @SlackHQ kinda silly problem, but i tried to upload :meow_lurk: from @slackmojis (it's an animated png) and it previews correctly, but when used in slack it appears empty. any thoughts?

  • johnhpage LordyTapes (@johnhpage) reported

    @SlackHQ RaaS Recalls as a Service

  • fearmyjargon Gary J. Foreman (@fearmyjargon) reported

    @SlackHQ I love the different messages when I click 'All unreads', but I've still got an unread thread that I can't find. I'm a pedant, and it's annoying AF. Help, please.

  • powcannabis A (@powcannabis) reported

    cosmonaut pill down the hatch, resuming terrible mission @SlackHQ

  • _steve2_ Steve Mahoney (@_steve2_) reported

    Hey @servicenow you bring up all my tickets you saw that problem for me like you reduce 90% of my work Can you work with them Bret @btaylor HMU on @SlackHQ use private pod

  • LopezForAmerica Anthony Lopez (@LopezForAmerica) reported

    Drafts are cool but I need to schedule messages to people on @SlackHQ to help me navigate my insomniatic periods

  • tweeetbro Funny Molecule 🍻 (@tweeetbro) reported

    @SlackHQ - Are you having issues again? Seeing frequent connectivity issues.

  • mattbarrio Matt Barrio (@mattbarrio) reported

    @nsnwca @SlackHQ This was such a terrible switch for myself. Having quick channel/DM info is super convenient. Quickly glance at timezone, channel description, profile info. Now I have to >click< through multiple times to get the info I need #productivityKiller

  • chriscardinal chriscardinal (@chriscardinal) reported

    @SlackHQ any idea why my VERY simple submit form workflow results in a "we had some trouble connecting" error like half the time?

  • Mbussonn Matthias​ ​Bussonnier (@Mbussonn) reported

    @SlackHQ That's on @Apple side here imho they should suggest users to unhide, or have a better error/warning messages, not you.

  • ruben_hauser Ruben Hauser (@ruben_hauser) reported

    The biggest problem with the iPad (Pro) is not iPadOS, it’s the ****** tablet apps from @GoogleWorkspace, @asana and @SlackHQ.

  • EngineerJohnO jobelenus.eng 💉🎉 (@EngineerJohnO) reported

    @rands @SlackHQ The window of time where you could have solved this problem has past ;)

  • byyournadi Nad (@byyournadi) reported

    @SlackHQ hello, since yesterday your apps aren't working properly to sending any files, it always failed to send, even after I updated the apps, it gets even worse. What happens and how to fix it?

  • cloakedninjas Daniel Jackson (@cloakedninjas) reported

    @SlackHQ Fine if you want to "dumb things down" could you at least think of power users? Provide the old functionality behind a checkbox in settings. Some of us like to see the user list without it obscuring the messages.

  • OGP93 Oskar Hope-Paulsrud (@OGP93) reported

    @SlackHQ Nice og you to ask, it's not to much a only slack problem and more like s computer who needs replacing and loads of background processes that I need to sort out. Slack is only eating 123,7 MB

  • rdohms Rafael Dohms (@rdohms) reported

    I'm not sure what @SlackHQ did.. but scrolling history with a mouse wheel is motion sickness inducing now... the infinite scroll keep jumping up and down.

  • alextharv Alex (@alextharv) reported

    @SlackHQ Hey! Like: it's so easy to start a call. 'draw on screen' feature. Useful. Don't like: Can take easily 10 secs between starting the call, someone answering and the call ACTUALLY STARTING. Regular quality issues. Weird sync issue with phone and laptop when someone calls.

  • phalanges dr. amanda pogue (@phalanges) reported

    @SlackHQ turns out simply changing the file type to .gif did not fix it, but converting it to a gif did. :meow_lurk: liiiiiiiiiives

  • ShaunOpoku Master of Hodling (@ShaunOpoku) reported

    @SlackHQ When I edit a message on the mobile @slack app it doesn’t reflect, same for when I pin messages also. There’s also a lag for when messages display when someone messages me, please help!

  • niet_lezen Do not read RCX (@niet_lezen) reported

    @SlackHQ Thanks Slack, I hope you can fix that annoying bar sooner rather than later. Animated emoji are sadly absolutely key to my work experience, so those have to stay

  • christoiwas Christo Harrison (@christoiwas) reported

    @duckfat @SlackHQ 4 months on, still a problem.

  • tweeetbro Funny Molecule 🍻 (@tweeetbro) reported

    @SlackHQ The issues on the platform are far too frequent, considering lot of people rely on it and this disrupts work every time it happens.

  • SadCustomers Customer Service Hell (@SadCustomers) reported

    @ExpediaGroup @chrisjburgess @SlackHQ This tweet frustrates me...a lot. You have tens of thousands of customers at all of your companies who are given little to no Support when problems arise and they're miserable because of it, and yet you are pushing a mindfulness initiative here? Where's the mindfulness for THEM?

  • NicoSchottelius Nico Schottelius (@NicoSchottelius) reported

    For a few weeks I am having trouble to load @SlackHQ in the browser, sometimes leading to an error messages, sometimes delaying for some minutes. Other sites work fast, speedtest shows 500mbit/500mbit/s. Is that only me or a known problem?

  • dalanMendonca Dalan Mendonca (@dalanMendonca) reported

    @shilpiagrawal55 @SlackHQ Terrible line spacing, couldn't recognise my own message after posting

  • moeffju a ******* neurodiverse they/them catgirl hacker (@moeffju) reported

    @SlackHQ Is there some issue in your systems? Uploaded files are flickering in and out of existence

  • oscar_apeland Oscar Apeland (@oscar_apeland) reported

    @zats @SlackHQ I imagine this is just annoyed customer support who’s had it with people who can’t remember their login email. Many platforms who use email as primary is for all third party auths has this problem now.
