    @SlackHQ Latest version on snap is borked. Kubuntu 22.04. Crashes before it opens. Sorry I didn't get an error for you before I reverted back to 4.28.182. For those wondering `sudo snap revert slack` will save you for now.

  • OptimusOnlineNL Optimus Online - SEO-bureau (@OptimusOnlineNL) reported

    @timsoulo @SlackHQ I’m forced to, but I hate it. Doesn’t work well for my neurodiverse brain. UI and UX are terrible.

  • CodingGimmic ˗ˏˋ Jahkamso ˎˊ˗ (@CodingGimmic) reported

    @SlackHQ I haven't checked on browser, the issue is showing on the desktop app. I'll run the test now

  • relequestual Ben Hutton (@relequestual) reported

    This morning I've wasted a good 1.5 hours because the @SlackHQ logo for the @github provided integration is all green as opposed to the acutal colour of the logo/icon in the list of Installed GitHub Apps 🥲. The code is no longer open source, so how do we fix this?

  • CaptFWA TheFlyingVC™ (@CaptFWA) reported from Manhattan, New York

    @SlackHQ Will that solve the view preferences on the app?. That is where the problem is, not on desktop.

  • RJMcCollam RJ McCollam (@RJMcCollam) reported

    Is @SlackHQ still having issues with thread read status? I can’t seem to shake off the unread bubble for a thread from yesterday morning.

  • Thickaaz Princess CMgr MCMI (@Thickaaz) reported

    @SlackHQ is Slack (app) down? I can’t send messages or react to anything without getting an instant ‘Try Again’ response 😩 #SlackDown

  • CaptFWA TheFlyingVC™ (@CaptFWA) reported from Manhattan, New York

    @SlackHQ: It is HIGHLY frustrating to view an unread message icon on the app to only DISAPPEAR when you open the correct channel. Why doesn’t the new message STAY put?. This is highly inefficient especially when one has multiple slack channels!. Is there a fix?.

  • Jazinity Jazzy 💕 (@Jazinity) reported

    @Sacheverell @SlackHQ Been working fine for us all day, you sure it’s not a local issue?

  • dave_stewart Dave Stewart (@dave_stewart) reported

    Amazing that @SlackHQ's lack of channel groups keeps me up at night. Having to negotiate channel name prefixes with the team should not be a problem in 2022 🤦

  • elijahmanor Elijah Manor (@elijahmanor) reported

    @dceddia @SlackHQ Yes, it does appear that way. Weird. Guess some glitch in the matrix

  • blackgik blackgik.eth👓 (@blackgik) reported

    @SlackHQ For some weird reason, Slack does not open on my system and mobile device. a team mate is experiencing the same issue. It comes and then stops. Can I have a call with a technical team?

  • PrayanshRatan Prayansh Ratan (@PrayanshRatan) reported

    @SlackHQ should learn something from WhatsApp and go down once in a while #whatsappdown

  • d_feldman Daniel Feldman (@d_feldman) reported

    @worldwise001 @SlackHQ A previous job made backup software It couldn’t handle dates post 2038 Kind of a problem since some companies specified retention times of up to 30 years

  • healthy_food Healthy Organic Food (@healthy_food) reported

    @SlackHQ We already tried and it does not work. This is a huge bug. Please provide a fix this week or we're moving to @discord

  • guyrleech Guy Leech (@guyrleech) reported from Wakefield, England

    @GabyGrau01 @SlackHQ I don't have a problem with that at all and do the same myself but on the next line will put the reason why I am contacting them or ask if they have a few minutes for a question now

  • 0xf7ank f7ank 🐨 | Designer (Product) (@0xf7ank) reported

    Yo! @SlackHQ I can't seem to get you to work. Are you down?

  • codename_VOA Victor, a foundational Edo boy (@codename_VOA) reported

    @SlackHQ I have been having troubles connecting to your website. On Google Chrome and Microsoft Edge site info it says your site is not secured and therefore the page can't be reached. Any way to fix this?

  • OSeyi_Shutters Oluwaseyi Adéyemí Ojo (@OSeyi_Shutters) reported

    @SlackHQ I hope that works this time, cause I've been trying to get help from your support group to no avail.

  • _saderico Fede (@_saderico) reported

    @a_hoverbear @GyenAbubakar @SlackHQ Where i kind find the definition of federated? Because i have seen it in different places in software, like frameworks, soap/soa and now for a chat service 🤔🤔

  • Lakshay_enth Lakshay.chawla (@Lakshay_enth) reported

    One company who was trying to build one metaverse game glitch but failed. The Company started again , raise capital and build @SlackHQ . Sometimes you fail but this is what Enterpunership is. Now people are failing in web3 = learning in web3.

  • taillogs Ryland (@taillogs) reported

    I can’t take it anymore. @SlackHQ my ios app experience for the last year is beyond terrible. Every single day dm read/unread status syncing breaks. Then those statuses are not only useless they actively waste my time. I know it can be better because it used to be.

  • nessicab Nessica Birwadkar (@nessicab) reported

    Making Meetings Async @SlackHQ for conversations, @loom for quick videos and Google docs for async comments. Do we want to spend 45 minutes on a meeting when a 5-Minute video and consequent async doubt-solving can sort the issue?

  • healthy_food Healthy Organic Food (@healthy_food) reported

    When is @SlackHQ going to get their act together and fix the freaking "Threads Staying Unread" issue that is affecting thousands of users? Time to move to @discord?
