Hi,
I’ve just installed a new Ring with chime device and I’m having the same problem. Volume can be adjusted, but not the chime tone.
Tried the suggested resolution, but I just get an error.
Samsung Galaxy S10
Android 10
Ring app 3.29.0
Firmware says its up to date
Tried wifi and mobile network
Tried reset
Not bothered with images or recordings as it doesn’t appear to have made any difference to other users with the same issue.
