The mic icon doesnt show or work

Hello me and my bf are using the site everyday for the past two years and now suddenly he cant use his mic
I usually type and he talks but now his mic icon isnt even showing
Meanwhile when i enabled my mic it worked
Btw i use a phone and he uses a pc

Thanks a lot for your bug report. “his mic icon isnt even showing” means he can’t see it on his side? Could he send me a screenshot to ? Thanks!
