    @SlackHQ is Slack down in Mumbai? I recently traveled from Boston, and reached yesterday , and since then Slack hasnt been working for me. It’s hindering all my work. Please confirm. Thanks

  • Miz_Marie Marie Whitehead (@Miz_Marie) reported

    @SlackHQ app won't let me sign in. Have tried email link, it sees my 2 workspaces which I have checked and I click next and it says it has encountered an error. Click next again and it goes into a loading loop and never loads. I have uninstalled, restarted and reinstalled.

  • far33d Fareed Mosavat (@far33d) reported

    @SlackHQ Hello friends! Long time, no tweets! When I close the threads view in the mac desktop app, the main message window doesn't re-expand to fit, leaving me with a big blank box on the right. Is this a known issue?

  • _catownes Catherine Townes (@_catownes) reported

    Help! Anyone having issues with @SlackHQ embed on a @NotionHQ page? Using the /slack command and it looks like it's constantly loading. Trying to see new messages from a Slack channel in the associated Notion page — is that even possible?

  • adam_zethraeus adam (@adam_zethraeus) reported

    .@SlackHQ can you fix your ios16-being-detected-as-jailbroken thing because I know I wasn’t meant to update my phone yet but that doesn’t stop me from feeling dumb.

  • edwardsanchez Ed Sanchez (@edwardsanchez) reported

    @Obliviusing @joekndy @SlackHQ Right, the problem is that when you talk to 50 different people rarely, it’s hard to remember all their names. I have to do a search for some subject or keyword I mentioned to them and hope it works. That’s when I can think of a keyword.

  • Cruftbox Michael Pusateri (@Cruftbox) reported

    @SlackHQ Your ingest process for custom emoji could use improvement. When uploading images within specs, they are rejected as "This image is a bit too big, even after resizing. A smaller file might help?" No clear error message and you have the compute to handle any conversion.

  • pierre_seznec Pierre 16nek (@pierre_seznec) reported

    @techvegetables @SlackHQ same here for ubuntu 20.04 4.27 snap & .deb are broken. downgrading fixed it

  • brenthealy Brent Healy ☁️ (@brenthealy) reported

    @loudmouthtechy @BringBackEV @SlackHQ Technology doesn’t fix culture

  • securityweekly Paul Asadoorian (@securityweekly) reported

    Got a weird error running Slack 4.27 on Ubuntu, crashes with "Attempt to write logs with no transports" and "Unable to create logs directory". Downgrade to 4.26 and its works just fine.. @SlackHQ

  • jelhan1 jelhan (@jelhan1) reported

    @SlackHQ @securityweekly Is there a ticket I could subscribe to be notified when it is fixed? I run into the same issue as described by @securityweekly.

  • denravonska denravonska (@denravonska) reported

    @SlackHQ @fortyseven Same problem for me on Ubuntu 22.04.

  • tbanting tbanting (@tbanting) reported

    @BobRomano19 Interesting. So looking at @SlackHQ - by adding voice and video huddles, does that make it more #UCaaS? - after all, I wouldn't need to dial a phone number or use a conferencing service/bridge?

  • zuccsleftnut Ay Makarena (@zuccsleftnut) reported

    @SlackHQ hey. I’m having some issues with my app and even opening on desktop. I cannot open the app or desktop app on my wifi network. It only opens when I use my mobile data. Even on desktop browser it opens only when I connect through VPN. What’s happening?

  • luiscvega Luis (@luiscvega) reported

    @SlackHQ Slack Desktop v4.27.154 for Ubuntu is not working. The recent update broke it for me. Electron Debug log says “Floss manager not present, cannot set Floss enable/disable”. I’m running on Ubuntu 22.04. Using .deb package. Can you fix?

  • tjhorner (@tjhorner) reported

    @Zoom @SlackHQ I tried re-adding the app entirely but still broken, L

  • mbootsman Marcel 🇺🇦 (@mbootsman) reported

    @SlackHQ when I want to set a reminder for next week, I expect a reminder in 7 days, not on the Monday of coming week. Can you please fix this?

  • tjhorner (@tjhorner) reported

    is the /zoom command broken in slack for anyone else @Zoom @SlackHQ help

  • arkamthebard Arkam The Bard (@arkamthebard) reported

    @SlackHQ is the Giphy integration broken? Doesn't seem to be working.

  • josh7weaver Joshua Weaver (@josh7weaver) reported

    @SlackHQ Following these instructions to add fields to user profiles and step 5 ("Publish Changes") doesn't work... at all. I click the button and nothing happens. Refresh and changes are gone. Tried on mac/pc chrome/ffx/etc, same bug. HELP!!!! @canopyteam1

  • AshhadDev ashhadsheikh (@AshhadDev) reported

    @SlackHQ there's a constant glitch with huddle, it keeps disconnecting and re-connecting.

  • michaelhood Michael Hood (@michaelhood) reported

    @SlackHQ hi! feat/fix req for iOS app, re: notifications for threads within DMs. If I have the app open to a DM it treats it like the *threads within that DM* are in-focus: no in-app notifications for them. Even if they're offscreen/older. This also doesn't match desktop behavior

  • Obliviusing Oblivius (@Obliviusing) reported

    @edwardsanchez @joekndy @SlackHQ Direct messages “disappearing” is an issue - but if you know who you were messaging with, they can be found again - just open a direct chat with the same people.

  • christianh814 Christian Hernandez (@christianh814) reported

    @vwbusguy @mattdm @SlackHQ I've been using the Flatpak without issue. However, it would be nice if it was officially supported.

  • mayank33en Mayank Tiwari (@mayank33en) reported

    @SlackHQ nope. not working. Tried via both google chroma nd safari.

  • haripittar Hari B Kurup (@haripittar) reported

    @SlackHQ launched slack on Windows 10 but the GUI just wouldn’t appear. Uninstalled and reinstalled the latest version but that doesn’t help either. What’s the solution?

  • scottfweintraub Scott Weintraub (@scottfweintraub) reported

    @SlackHQ I really hope you’ve improved huddle performance. My experience has been that people cant hear me when I screen share, an issue no other comparable tool has had, on a 100 up/20 down line.

  • jakebathman Jake (@jakebathman) reported

    Hey @Zoom @SlackHQ my /zoom command in Slack isn't working (there's no response after using it). /zoom help shows commands and I've tried logging out and re-authing the Slack app. Not sure which of you to hit up for support on this? Others in our workspace are also having issues

  • planetf1 Nigel Jones (@planetf1) reported

    @adam_zethraeus @SlackHQ It’s frustrating. Hope slack find a way soon. I’m sticking with the beta, just can’t work with enterprise slack channels. Literally only app I have any issues with (device is mdm, corp outlook etc). Just slack jailbreak detection

  • techvegetables Bradley Hamilton (@techvegetables) reported

    @SlackHQ Updating to 4.27.154 Linux client this AM broken my local slack install. Had to downgrade to 4.26.1 to get working again.
