Fenix 7 Pro SS buttons stopped working after 2 sea swims

So mu second Fenix 7 Pro SS broke after 2 sea swims (my first one broke also after a sea swim, even though I regularly rinsed it with fresh water.. got it exchanged for the new one). I had it for 3 weeks only..

Does this happen with all Fenix 7 Pro watches, or am I just really unlucky?

Should I consider switching to a different watch/brand? I need my watch for swimming, running and biking.
