Thanks, I had done that, but I didn’t know if there was a setting specifically to block any connections automatically.Make sure you have done this on your other iOS devices as well.
- Connect your AirPods to the iPhone.
- Open Settings.
- Tap Bluetooth.
- Find your AirPods in the connected devices list and press the small (i) button on the right of the row.
- Tap ‘Connect to this iPhone’ setting.
- Change the setting from ‘Automatically’ to ‘When Last Connected to This iPhone’.
