Airpods pro 2 connect perfectly with Iphone 13 pro. But when connected to apple watch 8 airpods only work one at a time. I have tried everything to remedy this, nothing works. All devices are up to date, charged and clean.

If you can’t connect your Bluetooth accessory or it won’t reconnect:

1. If you see  on your watch face, Airplane Mode is on. On your Apple Watch, tap Settings > Airplane Mode, then turn it off. 
2. Make sure your accessory is fully charged and powered on.
3. If you see the accessory in Settings > Bluetooth on Apple Watch, but you can’t connect, use the steps above to unpair the accessory.
4. Try to pair the accessory again.

If you need help connecting or using a Bluetooth accessory with your Apple Watch, contact the manufacturer."
