  • Showvhick Showvhick Nath (@Showvhick) reported

    Dear @SlackHQ is your notification system in mac os app alright? I am part of two workspaces in Slack, but I don't get notification from the second channel. Even I turned on bounce icon option, it doesn't work. Should I do something to solve this problem?

  • coolaj86 AJ ONeal 🇬🇧 (@coolaj86) reported

    @SlackHQ Full-*** markdown is better than half-*** markdown every day of the week. I'd be willing to help get this implemented. Could probably cheat a little and see which library Discord is using for node. Since you ship native code anyway, goldmark and comrak would be better choices.

  • coolaj86 AJ ONeal 🇬🇧 (@coolaj86) reported

    @SlackHQ And, unless you're doing something that's just plain nuts (like interleaving markdown and other parsers in the same pass) this would literally be a one day to fix, one day to test type of change.

  • mattbrowndev Matt Brown (@mattbrowndev) reported

    @fredemmott @SlackHQ 1) s/WWW/facebook.com 2) Those proposals are maybe representative of a related issue — the people working on Hack are v. smart, often have backgrounds in academia, and don't bother with dumbed-down high-level introductions for the rest of us (because they don't need to)

  • Bluueer bluueer services and partners (@Bluueer) reported

    @ChrisO_edits @SlackHQ Hmmm we are not quite sure of the problam we will have a look for you, meanwhile try: 1. Restart your phone by holding down the power button and press restart 2. Force close all your apps 3. Re-install the app that is having this issue

  • zipporouge Michel Auclert (@zipporouge) reported

    @SlackHQ @timbuethe Just logout and login for me it worked.

  • Abhi9_b2 Abhinav Wagadre (@Abhi9_b2) reported

    @gauravmunjal I don't understand the problem with @SlackHQ .I miss slack badly in new org.

  • ruthbushi Ruth Bushi (@ruthbushi) reported

    @SlackHQ No error messages - it just doesn't respond, and doesn't appear in running programs either. I've managed to open it today, but only by going to the Slack website, then clicking the launch > open on desktop.

  • jonKzink Jon Zink (@jonKzink) reported

    @SlackHQ, why do threads go up in chronological order, while channels go down?

  • spatula75 Nicklas Johnson (@spatula75) reported

    @SlackHQ That only solves the problem for threads. When I get included in a conversation with a few other people, the same thing happens unless I mute the group. A simple "no more than 1 notification per minute" setting would mostly solve the problem.

  • MadPipeline Ovidiu-Florin Bogdan (@MadPipeline) reported

    @SlackHQ How do I report a bug with slack? My issue is: if Slack is set to use a specific microphone and I change the default microphone on linux, slack starts listening to the new default microphone.

  • nknowsn naresh (@nknowsn) reported

    @BehereBaba @WhatsApp @SlackHQ Nobody wants to talk or videocall. Would only do that if it is an important subject or issue.

  • MadDawgDesi Modus 1312 Pwnens (@MadDawgDesi) reported

    @SlackHQ @tazjin doesn't help at all. being able to leave group DMs like channels would be easier, please add this feature

  • kwaku_mikey Mike_kwaku (@kwaku_mikey) reported

    @Paapakwame @SlackHQ Why do you place emphasis on grammatical error? It could be a typo too.. Not every grammatical error on Slack is intentional.

  • pommie_tappet Pommie Tappet (@pommie_tappet) reported

    @SlackHQ The issue is that my watch (and my phone) vibrate and make a noise on *every single message received*. Whereas Discord seems smarter: it'll group messages together so that rather vibrating my wrist off, I get one notification per bunch. Makes sense?

  • ruthbushi Ruth Bushi (@ruthbushi) reported

    @SlackHQ Hello. Are there any issues with the Slack desktop app? I can access my channels via Chrome, but my desktop app won't open since last week (Win 10). Any advice? Thanks.

  • TheOriginalWok Satoshi's Wok (@TheOriginalWok) reported

    Hey @SlackHQ whenever i click on magic login link and get a message saying it expired. I think receive an email saying someone from Belgium logged into my account. I'm in the UK. Happens over and over again. What's going on?

  • BaconRuffles Matthew Giardino (@BaconRuffles) reported

    @DinoMFX @SlackHQ Fine for me! Samsung s20 and having no issues

  • the_mikemark You can call me Mike (he/him)🏳️‍🌈 (@the_mikemark) reported

    Hello @SlackHQ, separating favourite chats in a different group doesn't work well because users try to find the alphabetic first and the two groups create the problem. I would suggest resizing favourite chats to a bigger size.

  • mballance William M. Ballance (@mballance) reported

    @WillAllred117 @SlackHQ RT, plus wknds: I dont want to forget to send so I hope notifications are off What's alternative? Keep a notepad of msgs to send in the morning/monday? A send later &/or snooze notifications would be great But then creates design issue of how to prioritize/stack notifications

  • nicoaferr nico (@nicoaferr) reported

    @megbutton @SlackHQ Yes it is. It’s one of their least-used features. The quality is terrible. Customers will continue to use best-in-class products, and Slack is incapable of producing best-in-class anything.

  • ChrisO_edits Chris Ogle (@ChrisO_edits) reported

    Hi @SlackHQ I have all notifications enabled on both Android & desktop app, but I'm still missing quite a lot of replies. In danger of getting seriously behind on work, please advise how to fix (PS have checked battery settings on Android & Slack is exempt) #slack #techhelp

  • BryanDickey_ Bryan Dickey 📲 (@BryanDickey_) reported from Nashville, Tennessee

    me (cst), sends: “can you do 2:30?” recipient (pst), should see: “can you do 12:30?” @slackhq help

  • artmasa Arturo Martinez (@artmasa) reported

    recently I upgraded my screen setup tp 3 4K displays to increase productivity while coding to find out that @electronjs enabled app bring down my video cards with such setup. A simple app like @MicrosoftTeams or @SlackHQ need to be closed to recover system resources.

  • paolocutilli Paolo Cutilli (@paolocutilli) reported

    @SlackHQ service unavailable, App in Linux and web page Am I missing something?

  • sippingoxiclean rach (@sippingoxiclean) reported

    @SlackHQ This only removes previews for the sender (which isn’t mentioned at all in the article you sent). The issue is that the images & other text previews are unnecessarily large. Prior messages get lost in the mix, especially during rapid back-and-forth conversations.

  • nicholashamlin Nick Hamlin (@nicholashamlin) reported

    @SlackHQ I also figured out that these link lengths vary a lot, but it's hard to tell in slack because they're abbreviated when displayed. This is why they were working fine before and just seemed to have recently had issues. Thanks for following up!

  • exchange12rocks Kirill Nikolaev (@exchange12rocks) reported

    @SlackHQ No errors The dot is just blank, like they are offline Yes, I am able to send messages Yes, network change does nothing

  • palash2504 ぱらしゅ (@palash2504) reported

    Is @SlackHQ down? I can't sign in

  • Rich_W17 Rich W (@Rich_W17) reported

    @SlackHQ Thanks! Is there a fix coming for the app, or would I need to uninstall this version and get the direct download?
