Watch: Fenix 5x+
FW: 10.0.0
Heaphones connected via bluetooth (Bose SoundSport - latest FW)
When playing music, or using Spotify the watch will drop the bluetooth connection to the headphones during an activity. After some investigation, restarting, resets etc I think the problem seems reproducible and is triggered when the watch is playing a tone/sound on the watch directly (alarm, lap beep, gps signal acquired beep, etc) - when turning off the audio signals/tone in the settings on the watch the bluetooth connection is not interrupted for the whole activity. When turning audio signals back in the problem comes back.
Please let me when this is fixed and if you need more information.
