Bluetooth connectivity lost after initially connecting, after a couple of minutes, with the latest updates installed.
I am able to initially connect to my bluetooth speaker. I then play a youtube video on firefox. In a couple of minutes, the phone disconnects from the speaker, and the video continues to play on the phone's speaker. I have filed a similar bug against UBPorts - but I was able to "fix" it by resetting the Pinephone in that case - https://gitlab.com/ubports/community-ports/pinephone/-/issues/201.
