Fenix 7 Sapphire Solar (button issues, mainly the "Back" button)

Hi,

I am wondering if this is a Fenix 7 issue or something not that common. How many Fenix 7 Sapphire Solar owners have issues with the Back button and sometimes with other buttons as well (for example when I wanted to turn it off, it was sending the emergency message to my contact, and could not cancel it due to the back button was not responsive at all.)

The story:

- I bought a Fenix 7 Sapphire Solar in September (replacing my Fenix 5)

- Back button stopped working after 2 weeks

- Got a replacement but in mid-January, the back button stopped working, got my 3rd watch

- After 3 days (and one swim), the back button is dead again

I am using it mainly for swimming (3-4 times/ week in the pool and 2x/week in the sea) and for other sports on the weekends. My assumption is that there is something to do with the sea swims, cause other swimmers with Fenix 7 do not have this issue.

Any help or feedback is appreciated cause it started driving me crazy.
