The condolences are appreciated ... :-)

Zoom's ugly as hell, but the Linux client has long been fairly reliable. Teams meanwhile is plagued by issues that don't seem to affect some other Electron-based apps or Chromium. During meetings it'll start out fine, then a minute in it'll suddenly use microphone. Opening any settings views tends to knock audio out of working state, too. Their official forums are full of threads on this, and support people suggesting crazy mitigations such as running it as root (admin user).

The most recent release seems to be from September 2021, which is positively ancient for something based on a browser engine and using it to display complex content from remote hosts.

Not least, it doesn't seem to allow include Yubikey access which is a bit of bummer when that becomes a company wide thing.

Then again Microsoft sites don't seem to work with security keys in Firefox either.
