2020 Sierra 2500 Denali.  Same issue and the "fix" (sounds and haptics) does not work.  I Phone XR with latest update as of today.  Also, updated latest software for the truck.   Frustrating.  For now I have just disconnected my BT from the vehicle.  


I have also had issues with radio muting itself with no fix until the engine is turned off for a couple minutes.

Checked both of my phones, and neither one have "Change with Buttons" turned on.  Just got the truck a week ago, and this has already become annoying.  Will check the version on my Infotainment as well.
