Just got iPhone 11pro w iOS 13.7 and wish I had seen all the threads about bluetooth issues w this iPhone model as coming from an iP8 and never ever got disconnected unless walked to far from speakers, never ever had phone headset disconnect and now it drops after 5 minutes and doesn't re-connect.

Please let me know if Apple has a fix for this yet?

Thank you!
