Mic not working for calls with new AirPods 3rd
I have new 3rd Gen AirPods that are having an issue where they are connected and I can hear everything I'm supposed to but anytime I answer a call or place a call the called person cannot hear me. If switch to iPhone or Speaker in the call screen menu and then back to AirPods they work fine. If I make a call using "hey Siri" the mic works because Siri places the call but when the person I call answers they cannot hear me. Again, if I switch the audio away from AirPods and back again they work fine.
I've changed settings for Automatic Ear Detection, Connect to This iPhone, and settings for Microphone auto switch or always left or right. I've also reset the AirPods, forget them and reconnected, made sure my iPhone 13 pro is up to date and there is no issue with the mic being dirty or blocked. I've also tested the mic with voice memo app and it works fine. This problem seems to be limited to calls only and I'm stumped and very frustrated. Any additional ideas for a home fix would be greatly appreciated, I'd rather not spend half a day at the Genius Bar or send them in for repair/replacement. Thank you.
