Just want to say I've got the same problem on Pixel 7a.
Seems obvious to conclude it's only affecting Pixel phones. I'm using the paid version so I would love to see a patch to fix this. Do we have any news from the Devs?
My Pixel 8 pro has been doing this for months. Android auto, blue tooth devices - seems anything bluetooth
sometimes plays two songs I think, sometimes hangs on every transition to the next song but always plays the song if you hit the last song button.
silent song is playing just no bluetooth output. Really annoying and a constant distraction while driving.
