Jayzar,
I have the same issue that was described by Chris.
Around the similar timeframe, my MS Teams no longer has an option for bluetooth when selecting the speaker/audio output. This has been independent of the device my phone (Google Pixel 3) is connected to. This has occurred when connected to my car bluetooth or my head set (Samsung Buds Pro). Please note that approximately 7 days ago, MS Teams did give the option to connect to a bluetooth audio device, but now the choices when you press the audio choices: Device (which would be my phone), Speaker, or Mute.
I have tested this on my business cell phone (Samsung S22+) and works fine. Even tried calling my other phone and when looking side by side, the audio choices on the Samsung S22+ are: Device, Bluetooth, Speaker or Mute.
Versions of MS Teams are the same on both devices.
