    @SlackHQ @SirCharlesW727 Let's see, it's 2021 and @SlackHQ still has trouble with .mov files, quicktime files, videos from an iPhone using standard codecs. So frustrating.

  • dantrim1134 Daniel Joseph Antrim (@dantrim1134) reported

    @dnsmichi oh that makes sense, thanks @dnsmichi! i guess i am just used to other things like @SlackHQ where i typically just muscle memory towards ":thumbs<Enter>" (which is hinted at in that issue)

  • tony873004 Tony Dunn (@tony873004) reported

    @kat_volk @SlackHQ A lot of programs do that. All my important emails are quickly demoted to page 2 and 3. Then I get in trouble for not seeing them.

  • TheAlmightyShid Nick (AKA: Shid) (@TheAlmightyShid) reported

    Morning @SlackHQ ! I wanted to suggest a feature that I believe would help many remote companies right now capture some of the drive-by conversation magic that was lost when people canceled leases or went full distance. The feature that I would like to have are voice channels

  • biswajeeta Biswajeeta (@biswajeeta) reported

    @SlackHQ web down?

  • TChanaH Chanaka Hettige (@TChanaH) reported

    @SlackHQ My windows 10 is bit bugged at the moment. It might be a side result of that. Planning to reinstall windows towards May. I'll ping you guys if the issue persist after that. Thanks! (I only remembered this now)

  • Sir_Frag Frag (@Sir_Frag) reported

    @figmadesign @SlackHQ Not working fix plz

  • danielsavface Daniel Savage (@danielsavface) reported

    @SlackHQ can we fix this now given u that probs have a lot of pandemic money

  • TheABM_Convos The ABM Conversations Podcast (@TheABM_Convos) reported

    Real product-led part happens in the mid-to-bottom funnel for most products unless there is an inherent virality like @Zoom or @SlackHQ . Unless people know that your product exists, product-led isn't gonna help. Therefore:

  • dnsmichi Michael Friedrich, a taste of austria 🇦🇹 (@dnsmichi) reported

    @dantrim1134 @SlackHQ Me too :) I remembered an earlier discussion, so I jumped in here. I don't know how to fix it though ;)

  • Kartik_Bhandari Kartik Bhandari (@Kartik_Bhandari) reported

    Seeing how @MicrosoftTeams is slow to replicate @SlackHQ, it obviously took them 2.5 months to replicate the Slack outage of 2021. #MicrosoftTeamsDown

  • martparve Mart Parve (@martparve) reported

    @jorgenmatsi @SlackHQ If it were my dissertation, I'd narrow it down by reaching back to emoji use _dynamics_ of good leavers and non-leavers, and see if predictive patterns emerge.

  • xxdesmus Justin (@xxdesmus) reported

    Do I know anyone at @SlackHQ who can help with an upgrade for a cross industry Trust & Safety Slack group? We need cross-Slack support in particular.

  • Coley4711 Adam Coley (@Coley4711) reported

    @SlackHQ It's still not working at all in Chrome and I've tried all the troubleshooting steps?

  • g_e_r_b Gerb (@g_e_r_b) reported

    @SlackHQ your service is good but your client app is bad. Not responsive. OS context menus sometimes work, sometimes go void. Making calls is impossible. If you are serious about replacing email, this is not the way forward.

  • Coley4711 Adam Coley (@Coley4711) reported

    Is it me or is anyone having performance/loading issues with #Slack at the moment? @SlackHQ

  • nicoaferr nico (@nicoaferr) reported

    Our team's @SlackHQ usage is down 14% since we started using @jointomo. 😯

  • tedrants Ted Gegoux (@tedrants) reported

    Anyone else think @SlackHQ needs a #vacationmode I always delete it from my phone when I go on vacation to help break the checking it habit.

  • SpokenLikeHer Apoorva (@SpokenLikeHer) reported

    @SlackHQ my slack notifications are muted even though my laptop's notifications and alerts are on. I didn't mute it myself. So any idea whats the issue?

  • cole_eliot Eliot Cole (@cole_eliot) reported

    @SlackHQ Sure, I mean, I'm only doing what I've stated above. It's repeatable (I forget the right term). I'm able to work around it, so it's not a big enough issue for me right now. But if it is, I'll get in touch.

  • taylorsturtz Taylor Sturtz (@taylorsturtz) reported

    Slack keeps adding features to assist new users with text formatting, slash commands, etc. but in doing so slows down savvy users trying to type without disruption. @SlackHQ #ux

  • HenleyRevees henley revees (@HenleyRevees) reported

    @robertjpayne @SlackHQ Please help me with my project

  • _dzen Ignacio Romero Z. (@_dzen) reported

    @farhadnoorzay Back in the days we would first think the Wi-Fi was down, before doubting @SlackHQ lol

  • jonomallanyk Jono Mallanyk (@jonomallanyk) reported

    @SlackHQ Thanks for the help! I was able to use Help > Troubleshooting > Clear Cache and Exit, which prevented me from being signed out of my other workspaces.

  • RejiYates #Faught @Shomicita Stan Account (@RejiYates) reported

    @SlackHQ I have a question I need help with.

  • TheRealAlanCruz Alan Cruz (@TheRealAlanCruz) reported

    @MicrosoftTeams is down. I wonder if the engineering team communicating about it via @SlackHQ

  • ankijain21 Ankit Jain (@ankijain21) reported

    So many problems in communication can be solved if @SlackHQ comes up with a voice message feature. Please do. 🙏🏼🙋🏻 #remoteworking

  • scissorsfiend Gail McCormick (@scissorsfiend) reported

    Thank you @SlackHQ for not blowing up my phone with notifications while I’m using the desktop client. @MicrosoftTeams you have to fix this. Holy moly it’s insane.

  • kristenlcoates Kristen Coates (she/her) (@kristenlcoates) reported

    @SlackHQ Sent you a DM about some custom emoji problems I'm having on mobile!

  • MatthewMezey Matthew Kalman Mezey (@MatthewMezey) reported

    @theasnow @SlackHQ @davmurik Scroll right down the bottom for lots of good further reading on CoPs. And skip the bits that are too Q Community-centric ;-)
