Hi,
Have been struggling with this issue for a few weeks.
Here's my hardware:
- Lenovo V15 G2
- Iphone 15 Pro
- Airpods Pro A2698 (version 6B34).
Just downloaded the Magicpods app which has fixed it.
I can now swap between laptop and phone easily for video and phone calls - microphone works no trouble.
MagicPods app is something like $2... not great you have to pay, but at least it's a cheap fix!
