Forerunner 955 solar bluetooth dropouts

Hi,

I have never been able to use my forerunner 955 solar for listening to music. A year ago, I installed spotify and downloaded offline tracks, but my apple airpods just kept disconnecting, no matter which wrist I kept my watch on. It would typically work for around 5 minutes, before disconnecting, and if I tried to reconnect, it would disconnect again within seconds.

Now I have bought new headphones from Shokz, and I am encountering the exact same problem. I have updated firmware, and this time I am not using the spotify app, but a podcast app. It works for some minutes, and then disconnects.

I have tried to google to see if anyone had similar problems, but didn't find anything.

Any suggestions on what to do?

Many thanks,
Villas
