When my D130 doorbell button is pressed my phone app immediately shows an incoming video call and rings.

The ringtone is a very soft and quiet Ding-donggg

I can't find anywhere in the Tapo app or the phone settings where this sound can be changed to something louder.

If I go to the app notifications and select doorbell there appears to be an option to select the notification sound. But it still plays the same quiet ding-donggg

Help! I keep missing my door callers!

Thanks.
