Vivoactive 3 music no longer playing music when connected to my headphones.

My vivoactive 3 music was working fine for months. I connect my headphones via bluetooth and listen to my Spotify music when running but about 3weeks ago it stopped working. Watch is working fine and syncs to app with all my details. It also connects and finds the headphones but wont play any music. I tried with other earphones and same result. But the earphones are working fine with my phone. Only thing i can think is that i updated the connect app.l around same time. Dont know what else to do
