Bluetooth Audio Stuttering on iPhone 11 Pro with iOS 13.3.1
The Problem:
When listening to audio using bluetooth headphones (multiple brands including Sony WF-1000XM3) there are intermittent breaks in the audio. Audio drops out for half a second at a time. Frequently enough to be really annoying.
There does seems to be a link to activity on the phone - e.g. locking the device or unlocking the device, an incoming notification banner at the top (even though these are silent and shouldn't affect the audio - it sometimes causes a stutter.
What I've tried:
I've tried restarting the devices, removing and re-adding on bluetooth. Different audio apps. Turning off "Hey Siri".
Would appreciate any help or advice - this is driving me crazy.
