Thank you for reporting this issue. Our team is aware of the issue, and is working on developing a fix. We will share an update as soon as one is available.
The fix for notifications not appearing/playing when Teams is minimized is rolling out to the public ring. We expect it to be rolled out 100% by the weekend – I’ll update this item at that point.

This issue seems to be back.
Multiple people that work within in a Citrix environment (opened fullscreen) who have Teams installed on the local laptop don't get the notification anymore (always worked for them) although they hear that someone is calling them within Citrix. Going outside of fullscreen Citrix does show the main Teams window, the sound of someone calling them can still be heard but they can not see (or accept for that matter) the call or pop-up.
This happened somewhere around +/- half November 2020.
