    @SlackHQ Hi 👋 Currently, we have a issue in iOS Slack app about Japanese keyboard: We cannot type halfwidth space. We get fullwidth space instead of it. Could you fix it? It's very inconvenient to type Slack commands. My ver. info: iOS 14.4, Slack app 21.02.10

  • helenlkupp Helen L Kupp (@helenlkupp) reported

    @lennysan @FutureForum @SlackHQ We’re new! Launched it last fall in the middle of everyone trying to figure out how to best navigate this huge change & now helping executives figure out “well what in the world does hybrid mean!?” as we stare down light at the end of the pandemic tunnel.

  • sidpalas Sid Palas (@sidpalas) reported

    I was just able to receive an error notification via @SlackHQ, view the failed container logs from kubernetes (more specifically @kubeflow), find the offending code in @GitHub and send a summary of the issue to my team... ...FROM MY PHONE!📱🤯

  • xethorn Michaël Ortali (@xethorn) reported

    Wouldn't it be nice if @SlackHQ could allow composing the UI? I have a channel that I always need to be open, and my fix right now is to have the browser open on one side, and slack app on the other. We're in 2021. 😔

  • dooberry14 Ryan (@dooberry14) reported

    @SlackHQ On this, the changes to sections made on the desktop app look to carry over onto mobile so it's not a big problem!

  • joshdholtz Josh “Now a dad” Holtz 💪🚀 (@joshdholtz) reported

    @SlackHQ That is so many workspaces I need to re-login to 😥

  • wannabegroncho Valentin (@wannabegroncho) reported

    @SlackHQ how do I turn off notifications for @helloslackbot? they are so annoying and I hate them. Please help.

  • teamhappily Team Happily (@teamhappily) reported

    During the pandemic, @SlackHQ employees report their productivity went up, desire for flexible hours went up, but their sense of #belonging at work went down.

  • DaveSchinkel Dave Schinkel (@DaveSchinkel) reported

    Why is slack’s mobile app so ******. It’s like half the posts bomb out @SlackHQ fix your **** please

  • tranz_maureen Maureen Ajepe (@tranz_maureen) reported

    Please, is it just me, or is Slack @SlackHQ down

  • ArthurMingard ~/👨🏻‍💻 (@ArthurMingard) reported

    @SlackHQ iOS emojis seem to be case sensitive whereas MacOS are not, for example :flag-GB: Is this a known issue? Would it be possible to force lowercase before rendering?

  • fredbenenson Maybe: Fred Benenson (@fredbenenson) reported

    @mwikkid @SlackHQ Yeah. The problem is it’s hard to get rid of the sound memory / trigger in my wetware!

  • Seemo Saleem Dabbous (@Seemo) reported

    @SlackHQ the last channel i was in is being marked read even though the actual channel is invisible unless swiped into view. Anyways I filed a bug and had a response that it's a known issue!

  • Mike_Kaminsky Michael Kaminsky (@Mike_Kaminsky) reported

    Thrilled that Locally Optimistic slack for data folks is now over 3k people! But we've got 800 weekly active users and our free plan only lasts about 2 weeks. We are open to all and have no way to monetize, so if anyone knows someone @SlackHQ who can pull strings plz help!

  • anubhav026 anubhav (@anubhav026) reported

    @SlackHQ It was looking like internet is down but internet was working fine. I think your server was down.

  • raravena80 Ricardo Aravena (@raravena80) reported

    @SlackHQ having issues?

  • dmyersturnbull Douglas MT (@dmyersturnbull) reported

    @SlackHQ @cr3 I understand that you're making Slack more accessible. I just wish it the formatting bar had been rolled out strictly after a fix to avoid affecting long-time users who are now too old to adjust quickly.

  • deeebeau Dave Beau (@deeebeau) reported

    @CoolAssPuppy @SlackHQ This is a known issue. Delete the app. Quit your job. Put your laptop in the prelabeled Fedex package. That should stop these.

  • meetshahdesign Meet Shah Design (@meetshahdesign) reported

    Hey @SlackHQ I'm unable to access the community I created a while ago nor I can find any termination email from your team. Please help! I want restart my community!!!

  • WoknRoll19 Davan (@WoknRoll19) reported

    @SlackHQ My colleague and I are being having this issue on our laptops 🧐

  • ruben_hauser Ruben Hauser (@ruben_hauser) reported

    The biggest problem for the iPad as a full fledged work horse? Most apps from the big players like @asana, @SlackHQ and @Google are a joke compared to their desktop/web apps and iOS apps (eg: missing features, different ux, no support for the new pointers).

  • LandSailor702 Jason C. (@LandSailor702) reported

    Heya @SlackHQ, the system refuses to update my new email address since I no longer have access to the old one. It sends the confirmation emails, but I can never login with it. What gives? Thanks!

  • bgvsky bgvc (@bgvsky) reported

    @SlackHQ Nice wait&see the futur call&cao option :) There are two steps: 1. We don't know external person, we are not partner (#Slack doesn't help here) 2. We are now partner we can work together (#Slack help & is useful here)

  • IrregularExpr Ben Woodford (@IrregularExpr) reported

    Day... I don't know any more... of @SlackHQ having an absolutely terrible WYSIWYG Markdown editor and @discord managing to do it right by formatting the text but not actually hiding the markdown

  • EvanMPatterson Evan Patterson (@EvanMPatterson) reported

    @SlackHQ is how I found out @LinkedIn was down. How did you know?

  • melchoyce Mel Choyce-Dwan (@melchoyce) reported

    @SergeyBiryukov @SlackHQ Ugghhh that's terrible 😞

  • blarusic Brendon LaRusic (@blarusic) reported

    @SlackHQ @zek99 Thought I'd jump in here to represent 2021. Threads are still terrible.

  • LongTran02 Long Tran (@LongTran02) reported

    Man I really want @SlackHQ notification to just be boil down to: when sending a message, you have to toggle to select whether you want to notify people or not. All this complex systems seems to be put together with duck tape and Zendesk issues and not at all what the user want.

  • mhauken Marius Hauken (@mhauken) reported

    @MarkWalkerDK @SlackHQ I'm having the same problem. My Slack iOS apps are now unusable. I have to scroll past 30 channels to get to my starred channels. It was much easier to get an overview when they were displayed like regular channels.

  • DeviceCoders Device Coders Inc. (@DeviceCoders) reported

    @SlackHQ If you want to pay me to show you how broken and worthless your login system is you can send me a pm. I'm not arguing with you about this.
