Instinct update to 11 - random freeze during the night

updated my instinct to 11.0,  6 days ago.

After the firmware update,  it is quite frequent that some functions stop working during the night.

In the morning the watch is quite often in the following status:

- the body battery monitoring is stopped and no more working

- the connection to the smartphone is no more working (no connection to Garmin Connect)

- maybe other issues, not checked in details.

Stop/start of the watch fix this issue.
