When I press next song on my widget (the one that shows up when telephone is locked), Spotify starts playing on my phone and disconnects from my reciver. I have a P20 pro and playing from Marantz cr511. If i go in to the app and choose Marantz in sources, it plays on reciver with no problem. If I change the song in the app, first logging in to my phone, it all works aswell. What can I do?
