  • Vincent_usa22 Vincent (@Vincent_usa22) reported

    @SlackHQ I won't use your service or product as long as it's advertised on #BigTech platforms that censors American people. #BigTechCensorship #DrainTheTwitter

  • elsassph Philippe Elsass (@elsassph) reported

    @SlackHQ do I need to remove/reinstall Slack Android to fix the blank emojis?

  • KrazyChicknLady Sarah Bergen (@KrazyChicknLady) reported

    @SlackHQ Just started using your app for work! But emojis are not appearing on my Android 😭 (works fine on PC) Is there a fix?

  • andreatrasatti Andrea Trasatti 🤌 (@andreatrasatti) reported

    @SlackHQ It's not hard, it's SLOW! Before I could type /invite @SlackHQ and hit enter; now I start typing, I need to use my mouse to confirm the verb, then for a private channel I must confirm I want to add people then a new modal loads and lets me pick names. SLOW and broken sequence

  • YigitPinarbasi Yiğit (@YigitPinarbasi) reported

    @SlackHQ Hey! I have a problem with calls. My AirPods working everywhere but Slack calls. I've tried everything but can hear or use my mic when I switch to AirPods. I've changed anything and just stopped working 2 days ago. H e l p m e . . .

  • superhabboboy Ward (@superhabboboy) reported

    @Something915 @SlackHQ I have the same issue

  • 0xfraq fraq (@0xfraq) reported

    @brusisceddu @SlackHQ @discourse Yep, totally agree it’s problematic to allow blocking a coworker, but they already figured they problem out. If they can put adding apps and inviting people behind a permission gate, they can do the same here.

  • stuherbert Stuart Herbert 🖤 (@stuherbert) reported

    Looks like @SlackHQ is having more problems today.

  • JiLilliput Jill Coulter (@JiLilliput) reported

    @SlackHQ @joemerante This definitely needs a fix ASAP. I missed two calls from my boss today because I was not aware of this bug. Saw it come up on my phone and immediately went to slack on my computer. it disconnected him from my phone both times. I am using PC windows 10, and have an iPhone.

  • brusisceddu Brüce-v2.0.21-Becker Ph.D. (@brusisceddu) reported

    @0xfraq @SlackHQ Everyone in my sphere wrote slackbots to implement HR policy. Sure, they kicked it down the road, and there's no "suspend" or "block" functionality, but it's hard to block people IRL (like in a real office) too. They should make @discourse for work.

  • rhuijben Rob Huijben (@rhuijben) reported

    @SlackHQ Seems it was just a hiccup, a moment later everything looked fine again. Got a bit nervous after the issues last time. Thanks for the reply anyway.

  • Aerohaveno Tim Richards (@Aerohaveno) reported

    @UKtraveleditor @SlackHQ @yarratrams Yeah I hate them. I’ve started tagging the advertisers to see if that will help.

  • dmilith Daniel Dettlaff (@dmilith) reported

    @SlackHQ Your service is so laggy today, I have to wait 15s for message to appear in my client…

  • jasongriffing Jason Griffing (@jasongriffing) reported

    @choiveer @SlackHQ There’s a sort of default assumption that we need to see and be notified about everything. Not unique to Slack. I’d love to see more focus from all software companies on tools to help me keep the noise down.

  • stuherbert Stuart Herbert 🖤 (@stuherbert) reported

    @SlackHQ Having trouble editing messages, and getting blank screens similar to how the client was during your most recent outage.

  • urbanturbanguy Gagan Singh (@urbanturbanguy) reported

    .@SlackHQ how do I bulk mark all messages from 2020 as read? I want start with a clean slate. I now have an Inbox0 problem with #slack. Actually an Inbox-Few-Hundered problem.

  • therriaultphd Andrew Therriault (@therriaultphd) reported

    @SlackHQ @zek99 Yeah so should we go complain to your manager (hi @salesforce) about this now then? I mean, it's been almost 4 years and threads are still terrible. Who thought it was good UX to make it harder for users to find messages? Or at least let us see them inline rather than hidden?

  • jirihelmich Jirka Helmich (@jirihelmich) reported

    Anyone who would help with automatically publishing Markdown documents from merged @github pull request to @SlackHQ in a form of a PDF? Tried to @zapier around it, but got stuck on getting the updated file from GitHub...

  • MoreScooters MORE SCOOTERS THAN EVER (@MoreScooters) reported

    @juliaferraioli @lizthegrey @SlackHQ they seem to think that this is a HR problem as an excuse to not put in the basic work

  • rafsalak Rafal Salak (@rafsalak) reported

    How do you communicate with your remote teams when @SlackHQ is down? Is pigeon post hipster enough?

  • mattarmitage Matt Armitage 🐙 (@mattarmitage) reported

    @Something915 @SlackHQ Same issue here. Android 10. Reset cache doesn't help. Just started yesterday I think.

  • rhuijben Rob Huijben (@rhuijben) reported

    @terminalfix @SlackHQ Yes, seems Slack is down

  • juliaferraioli julia ferraioli (@juliaferraioli) reported

    @leftoblique @SlackHQ So many OSS projects use Slack. It's not necessarily feasible to move them to Discord, especially for underrepresented groups. Slack needs to fix this.

  • leftoblique Dana Fried (@leftoblique) reported

    @juliaferraioli @SlackHQ Ah. I have heard that the inability to set separate avatars for different discord servers (at least with the same email address) can be a problem for some folks, but compared to not being able to self-moderate that seems like a minor issue.

  • Something915 gabe. (@Something915) reported

    @SlackHQ I'm having an issue on mobile where I can only see custom emoji; no smileys or thumbs up. Others on my team are as well

  • MadeBySkylar Skylar Sanford (@MadeBySkylar) reported

    We don’t need frills; no security, no video talk, no apps, no extra support. Nothing extra. @SlackHQ we just need a dumbed down, basic account with unlimited text and image history. Take @discord directly head on.

  • theecommlab eCOMM—LAB (@theecommlab) reported

    — B2B: Business to business When a business sells their product or service to another business. Example: When a business purchases an enterprise license for their staff to use @SlackHQ or @zoom_us

  • yoz Yoz Grahame (@yoz) reported

    @SlackHQ I strongly recommend making it easier to get out of that situation. The sign-in page took up the *entire* desktop app UI, which meant I couldn’t access my higher-priority workspaces (which were working fine) until I fixed this one unrelated problem.

  • choiveer Choi Veer (@choiveer) reported

    @jasongriffing @SlackHQ We need a new messaging and email manifesto. A global etiquette. It’s a cultural issue, not just a software one.

  • gregsdennis Greg Dennis - Black Lives Matter (@gregsdennis) reported

    @SlackHQ Such quick service
