Major issues with my fenix 6x Sapphire

I'm desparate..

I have major and strange issues with my fenix 6x sapphire.

  • When I try to start an activity the activity list now empty, only one big green choice "add new".
    • Cannot use the back button to get back to the main screen.
  • Randomly a "Storm warning" (translated from norwegian) appears, multiple times.
  • Cannot connect to Garmin connect app (Samsung S20)
  • When I press and hold the Light button, every meny item (alarm, time zone, wallet etc) has the power off symbol! See picture below.
  • ++++

I've tried to reinstall the software, tried the beta 19.21, but no luck...

Any tips would be appreciated, thanks
