  • shirleman BLM Scott Hirleman (@shirleman) reported

    Any @SlackHQ admin experts out there? I want to basically add all domains of everyone who has tried to get into my Slack to be auto approved and the thing gives me an incomprehensible error about not allowing undefined.

  • shirleman BLM Scott Hirleman (@shirleman) reported

    @antonmry @SlackHQ You need a domain and we can't add email domains, that's broken

  • sashmograph Sasha Endoh 🌹🧑🏻‍💻🧙🏻🌈 (@sashmograph) reported

    @aurooba @LocalWP @SlackHQ 💯 and we persevered through the most unnecessary/nonexistent code error situation 🤜🤛

  • dnlutz Daniel Utz (@dnlutz) reported

    @SlackHQ it works now. i downloaded again by clicking on the button at the left. the problem is „silicone“. nobody gets it …

  • ThijsToday Thijs (@ThijsToday) reported

    @dashorst @SlackHQ The other end here :) I don't get any error, I receive other messages from Martijn after the missing formatted message. Just one formatted message is missing. It's missing both on windows app as on the android app

  • dashorst Martijn Dashorst (@dashorst) reported

    @SlackHQ text only, no errors. Was formatted code pasted from one message to another on ios that didnt get through

  • maslowbeer Sean Stoner (@maslowbeer) reported

    @SlackHQ I cannot pin it down on a particular thing. It happens somewhat frequently and sometimes when it happens it happens in rapid succession to the point where the system modal says slack keeps crashing. Definitely something related to this release though.

  • FryeX Samuli Järvinen (@FryeX) reported

    @AdamTReineke @SlackHQ Fully agree with this. Should have been more clear. I did spend time trying to find a setting that would fix it for me before posting.

  • hpauer_tw Helmut Pauer 🇪🇺 (@hpauer_tw) reported

    @flowolf @SlackHQ For some reason they tend to pop up as unread messages long after call. :-) But otherwise I have to say I don't really encounter issues with slack. It's quite robust.

  • derek_maurer Derek (@derek_maurer) reported

    . @SlackHQ Can we get a feature that limits conversation to one notification per mention? This could help the sanity of the recipients of those that like to live stream their brain in DMs.

  • WolfSparrowPub Teresa ☕️ Book Cover Designer (@WolfSparrowPub) reported

    @SlackHQ Hey, I have an issue on iOS where I will send a message and then that message reappears in the text field again, even after it's been sent. Do you know what's causing this? (And this is after clearing the cache and restarting the phone.)

  • its_theDai_show Dai Chanel (@its_theDai_show) reported

    @SlackHQ I’ve been kicked out of one of my channels 😩 please help!

  • southro_p ロップ (@southro_p) reported

    It seems @SlackHQ disabled autocomplete on their login form. That's quite annoying...

  • DavidRalston RalstoninBoston (@DavidRalston) reported

    @danieljpeter @SlackHQ @btaylor It's just me, right? I'm the only one that doesn't understand what Slack is or why one needs it? I'll sit down and be quiet.

  • turles144 Turles144 (@turles144) reported

    @SlackHQ @anderskleve Still happening in 2021. Still no instructions or buttons on the window or F11 support. I'd bet lots of people are googling this thread to figure out how to fix it when it happens.

  • pelavarre Pat LaVarre (@pelavarre) reported

    @mdcarini @NovallSwift Can we get @/SlackHQ to fix the bug where choosing an alias as your reactji corrupts the transcript to say you chose the original? Like when I choose :thank you-jp: as my reactji, Slack goes and tells everyone that I chose :pray: I didn’t, but it says I did Lying is wrong?

  • optemization temirlan 🪄 (@optemization) reported

    is AWS down or something? having trouble with @NotionHQ , @SlackHQ and bunch of others

  • shirleman BLM Scott Hirleman (@shirleman) reported

    @antonmry @SlackHQ It's not documented at all but apparently, it is that you can't open it up to general email addresses (gmail, yahoo, hotmail, outlook, etc.). And the error code makes no sense. It was really terrible UI

  • kontrafiktion Victor Volle (@kontrafiktion) reported

    Whoever writes the @SlackHQ release notes. They are the best. Most just write the same “we are always fixing bugs and improve stuff”. @SlackHQ always write about at least one understandable fix/improvement and that in a slightly funny way. And it doesn’t feel forced funny

  • TrevorLongino Trevor Longino (@TrevorLongino) reported

    @optemization @NotionHQ @SlackHQ I've been stupidly trying to fix my home internet, because everything I use every day is out, and then I realize it's an outage. 🤓

  • dbigpot Digvijay Mahapatra (@dbigpot) reported

    @akshay_moorthy @SlackHQ Personally, I find threads very useful. Even in 1:1 chats. It helps better organize the messages. For example, if I'm talking about a certain issue, all messages that have anything to do with the issue stays under that one thread and doesn't get mixed with other messages.

  • AnnHawkins Ann Hawkins (@AnnHawkins) reported

    @SlackHQ I think the real problem is that on Facebook, LinkedIn, Twitter etc, a reply (in thread - duh - what other reply is there?) is the obvious option. You can’t reply by starting a new conversation but in Slack that’s the default.

  • chadiamathurin Chadia Mathurin (@chadiamathurin) reported

    I think @SlackHQ reply feature needs to be made simpler. It does not make sense to me that I must hold a message down to reply to it or why I must tick a box for the reply to be sent as a direct message. I think WhatsApp's reply feature is a less hassle design.

  • itskrox •☆ john ochuro ☆ • (@itskrox) reported

    @optemization @NotionHQ @SlackHQ I'm also having trouble with Notion

  • coenhyde Coen Hyde (@coenhyde) reported

    I wish @SlackHQ had a "send message at .." in the recipients timezone. I hate sending messages to people in their down time knowing they may see it and think it about it, or worse action it.

  • TheWriterLuna Sakshi Udavant (Luna) (@TheWriterLuna) reported

    Is @SlackHQ down again!?

  • LegoRunMan Rudi🌲 (@LegoRunMan) reported

    @optemization @NotionHQ @SlackHQ Notion is down with no offline mode or other way to get your data...

  • dannysmith Danny Smith (@dannysmith) reported

    @optemization @NotionHQ @SlackHQ Notion problem looks like a DNS thing. Slack seems to be okay for me.

  • deeperbeats Jessie Nelson (@deeperbeats) reported

    @SlackHQ Having connectivity issues, did troubleshooting, it's still not working. I can't get it to load in my browser.
