For me the connectivity has improved. With previous firmware, I tried listening music with my Garmin Fenix 6S. It would connect and start playing, but very quickly (under one minute) either right or left channel would go quiet, and then eventually all music would stop. Fenix shows APP2 are connected, but no sound.
With new firmware, I have no such issues with Fenix, I have now played several hours without any audio drops 👍
