Middle of song interruption

[Diegorod]

I have been have a very frustrating issue. 1) when listening to a song while driving, my song would randomly start playing on someone else’s unrelated device. My music continues playing, but I am unable to listen. Also the app shows my song is playing and I see a device I do not recognize. 2) I am listen and someone else’s music starts playing on my device. When I look at the app, it says do you want to continue listening to the persons app. The connection is by itself and after I cancel and resume my music it continues to reconnect to the other unknown device. The devices being connected is not paired to my device or a device on my family plan.
