Background settings doesn't work when Teams not logged in and joining call as guest
Background blur settings is blank and doesn't work when Teams is not logged in and used for guest access.
the feature does not work for Guests for some reason ...
I see the exact same issue! That said, somehow, if I completely uninstall and then reinstall Teams from scratch using what is probably the installer for an old version (that I have downloaded in the past), then it usually magically works...
