    @johncutlefish @SlackHQ Checking messages on my slack spaces: Hello! Great to meet you! Have you seen that there’s a new editor? It’s waaayyy better! Me: yep, I just saw this message literally 10 seconds ago. They need to fix how they do #onboarding

  • esamek Evan Samek (@esamek) reported

    @SlackHQ any eta on the update to the bug that causes a smaller than necessary textarea to appear in the compose message area? My engineering colleagues asked me to tweet at you for an eta on a fix. #UXAsAMessenger

  • lithiumfox Lith Fox | 3 Years and still haven't done a debut (@lithiumfox) reported

    @itschrislama @SlackHQ .... >_> You don't understand.... Some of our "off topic" conversations can be like 100+ messages long In a "please help me" channel.

  • warty9 John Hawley (@warty9) reported

    @vwbusguy @SlackHQ I sorta maybe get @SlackHQ 's want to stop packaging for Fedora. They are wrong however, and Snaps is not the universal fix-all they want (it's not even seriously universal, properly support Flatpack if you want that). Wonder if there's a slack version of Heisenbridge

  • EdemT Edem Oyinkansola T (@EdemT) reported

    Is @SlackHQ down? Can't seem to connect on the computer or phone 😩

  • type__error Sophie Koonin (@type__error) reported

    @_phzn @SlackHQ @SHEChoirLDN Unfortunately I don't think I'd get them on there, I have enough trouble getting them to use Slack!

  • postnick Nick Post (@postnick) reported

    @jeremy_soller @SlackHQ Having never used slack. I still think this is a web app, and they can make flatpak and problem solved.

  • StanislavSulima Stanislav Sulima (@StanislavSulima) reported

    Hi, @Grammarly. Quick question here: Grammarly Desktop, version 1.0.1.2, does not work with @SlackHQ 4.23.0 on macOS 12.1 anymore. Slack is not blocked in Grammarly. Anything I can do by myself to fix that? Or is it a known issue? Thx

  • JamoH_12 Jamo (@JamoH_12) reported

    @SlackHQ It's something broken with the login? Linux APP opens SSO web login successfully but after that the APP does nothing :(

  • RajShirolkar Bill Shirolkar (@RajShirolkar) reported

    @SlackHQ @yonidayan_ Facing this same issue on my home network. How was this solved? @SlackHQ

  • sahajsarup Sahaj Sarup @home 2/3 💉💉 (@sahajsarup) reported

    @vwbusguy @SlackHQ I'm wondering if this happens on the flatpak, not seeing this error on my end.

  • JamoH_12 Jamo (@JamoH_12) reported

    @SlackHQ It's something broken with the login? Linux APP won't login :(

  • mattrackburn Matt Rackburn (@mattrackburn) reported

    @SlackHQ @WelshBluebird I’m having these same issues now. Was there ever any resolution?

  • C_Lepkowski Christopher Lepkowski (@C_Lepkowski) reported

    @SlackHQ The thing is, the pitch for Slack Connect targets already-paying customers (like us), and encourages us to turn partners (clients and vendors) into paying customers too. Ok, but then if they leave their plan (we're still paying) channels are broken? That kills the incentive.

  • samdbeckham Sam Beckham  (@samdbeckham) reported

    @jheimbuck @SlackHQ @gitlab Haha, nope. GitLab is people messaging me personally. Slack is 90% noise. Going through GitLab todos now. I'm down to one page

  • avaolon AvalonStar (@avaolon) reported

    @SlackHQ your login system is hopelessly terrible. sending a code to log in to a workspace but the email never shows up, also what does "The code expires shortly" even mean? "shortly"... get a grip

  • ianand Ishan Anand (@ianand) reported

    @SlackHQ I make heavy use of those shortcuts and that's part of the problem. Context: I'm reading my unread threads feed 1. Realize I need to search slack for the answer to this unread thread. 2. Find the thread with the info I need. Copy the link to it. (continued...)

  • agiledoc Rob Woodgate (@agiledoc) reported

    @SlackHQ Sadly yes, but it looks like a retention policy has kicked in rather than there being a problem 😭

  • mguthaus Matt Guthaus (@mguthaus) reported

    @SlackHQ Why have separate accounts when all of mine use the same email login?

  • simplybastow Janna Bastow (@simplybastow) reported

    @johncutlefish @SlackHQ Yup. I think the main problem is that it creates a divide between what you're writing and the ongoing chat, with that formatting bar. It used to be a clean line between the two spaces, and now you have to scan up and down across a rarely used chunk of interface to keep up.

  • marcelopwerk Marcel Enderink (@marcelopwerk) reported

    @SlackHQ What it send sis not the problem. If we make a slack we invite people to be part of a team for a project. Slack is not invited and has no worth to the project. it should not be sending us gifs or remarks! I just don't understand! Internet if full of people having this problem.

  • rolfb Rolf Bjaanes (@rolfb) reported

    @slackhq Tested how Threads work now and found issues with contextual awareness as initial notification had passed. Channels doesn't indicate unread content in a thread in that channel and Threads doesn't indicate if you have been specifically mentioned in subscribed threads.

  • oh1tr oh1tr (@oh1tr) reported

    @SlackHQ This is still broken: Windows 10, after huddle, RDP window.

  • tedwards947 Tony Edwards (@tedwards947) reported

    I think @SlackHQ needs tabs for chats... it's clunky trying to find info in channels/threads to respond to a question and then have to scroll alllll the way down and remember who you were talking to & respond

  • BrynaTweets Bryna Corcoran (Br👁na) (@BrynaTweets) reported

    Remember last year when @SlackHQ went down the first day we were all back to work, and it was kinda like an accidental brilliant snow day marketing campaign?

  • karmeleonnn shawn. (@karmeleonnn) reported

    @SlackHQ I can't open the slack webapp on Edge 97, it says my browser is out of date, but the Slack help center says Edge >= 89 is supported. What gives?

  • abhagsain Anurag Bhagsain (@abhagsain) reported

    @SlackHQ in the new update not able to upload an image pasted through clipboard. It says uploaded but it disappears. However, if I upload from fs it gets uploaded. Please fix it, it's a hassle to save the screenshot to fs and then upload the image :|

  • pcolley_23 Patricia Colley (@pcolley_23) reported

    @johncutlefish @SarahVoegeli @SlackHQ Users w/adaptive efficiencies (pain tolerance, workarounds) are pegged 'expert users,' magically turning ux tech debt into training issues. Backlogs (esp B2B) are full of serious usability fails, buried under new vanity projects. The human cost doesn't matter; it isn't measured.

  • MaahBorloth Maiara Borloth *-* (@MaahBorloth) reported

    @warty9 @vwbusguy @SlackHQ I can't stop thanking forumhack on Instagram After contacting twitter support they was no help until I got recommended to forumhack who helped me in getting access
