Bluetooth issues help

Whenever I sit in the car I play music first, if I start playing a song from my playlist and then switch to a song that I search (Apple music) it looks like iDrive can't figure out what song is playing and just mutes it. I tried forgetting and adding again, deleting bmw connected app? But no luck... the song still says it's playing on my phone but no audio. When I plug aux it works fine so it's just the Bluetooth connection. I'm on iOS 14.

Also my USB cable when I plug it into my phone it always flashes on and off, I tried different cables but it keeps happening so I can't even plug my phone in with USB
