This is a frustrating issue. I've tried every possible fix I could find online up to an including a complete reset of the phone. Apple support can't find any problems with the bluetooth module on my iPhone 11. I am very unhappy with this. All the money we spend on the phone and things like Air Pod Pro that are suppose to have superior connectivity??? we should not be experiencing these types of issues by the time the OS is released to the public. End of rant. Thanks for listening :-)
