Are you guys working on the phantom mut glitch
No. No one has yet explained what it really is.
If you were actually muted, you couldn't post here in the forum.
If it is something real, use the bug report tool to let Support know. (You find the bug report tool on the Support page-- not in the forum.)
Which app and app version?
Is this what's being seen (web and app)?

Then it's not really a mute. I believe the app is hitting the same thing the website does and the banner on the website is the reason.
I think it's based on quick consecutive posts and may include replies and new topics in that. So if you post a little less often it's less likely to occur.
