Also facing many issues on iPhone 11 256GB. The AirPods keeps disconnecting, when I answer a call from my plantronics voyager focus doesn’t disconnect, but if i answer a call the volume is very low, if I call back - the volume is fine. I’ve managed to reproduce the issue constantly.
I’m honestly shocked that Apple doesn’t even apologize and ensure the issue is being looked at.
I’ve canceled my order for two iPhone 12 max phones as they will come with iOS14 which will have the same issue. Encourage all to do the same as we don’t know when it will get fixed and if it will ever really work as it did in the past.
