Hello today i had a problem. I went for a run. Firstly I have started music from my phone, to my BT headphones manually. Later I wanted to switch a song by watches (2 days ago it worked). However, after I pushed a next track button in my music widget, nothing happened. I tried to reset my watches, turn it on and off again. I tried to change default music player in my phone. But nothing helped me. The saddest thing is that two days ago, it worked. Can you guys help me ? I have JBL headphones.
