When I use iPhone to see the camera view live, I cannot listen to sound using Airpods, or any Bluetooth headset.

Dear Kenny, thank you for the mail. After testing, the camera does have problem (app crash and no sound when live view with BT) with the BT headset, especially IOS app. Issue has been reported and feedback to development team. Please stay with us for the study result and if we could solve it for the steaming and app parts. Thank you for kind understanding.
