When will the fix for WiFi issues on Fenix 6 be released?

I'm having trouble connecting to WiFi on my Fenix 6 ASIA Sapphire. Its currently on version 15.4 which is the latest available version. I've tried everything suggested in the blogs but nothing seems to help. It used to work when I first bought it and managed to connect to my Spotify account. Upon version updates it's not working anymore.
