I have a newish iPhone and airpods. I have my pods in much of the day. When my phone rings, it rings through the pods. When I answer, 7/10 times the call is first answered going through the pods, then transfers to the phone, and I have to hit the button on the phone to transfer it back to the pods, where I hear "...ello? Can you hear me? Are you there?" Just 5 seconds or so, but still dumb. This worked fine a few months ago. I have changed no settings.
