no bluetooth connection when autoupdate from v3.15 to v3.3

Ive always update to the beta versions, but when it autoupdate from v3.15 to v3.30 my 945 stopped being able to connect to my mobile phone, therefore cant sync with garmin connect.

I sync it thoughout wifi, but I wwould like to use the smartwatch features too.

Should I go back to v3.15 or should I wait till next v?

Thanks,
