A. Check the Bluetooth settings on your iPhone. Go to Settings > Bluetooth, and ensure that the audio codec settings are compatible with your Bluetooth devices. Sometimes, resetting the Bluetooth connection can help. Disconnect and reconnect the devices to see if the issue persists.
B. If the problem continues, try using a different Bluetooth device to see if the issue is specific to one device. This can help identify if the problem lies with the app or the Bluetooth device itself.
