Bluetooth & CarPlay shutting on/off radio every 5 seconds

I have a Cochlear Osia hearing aid. The iPhone Bluetooth / Mifi to the device is buggy. It will randomly switch “modes” in the accessibility screen anytime the phone is connect to more than one device like my car. This also happens seemingly randomly.

this also means I cannot use CarPlay and listen to the radio because it pauses the music every 5 seconds.

I’ve tried deleting and re-pairing everything and in different order. I’ve reset both my iPhone and my car system to get it to connect right.

I think this is a bug in the apple accessibility features. It keeps trying to change the mode of the hearing aid and this shuts it off in my ear and in the car every 5 seconds.

help?
