I have the Android version and see what you mean, looks like a Dec. 3rd update stated the on/off ring tone button, but I too am unable to find "the button".Great news?. So it seems. A new version of the IOS EZVIZ-app came out (vs 4.03). And the release notes say: "We added a button that allow users to turn on/off the ring tone on the DB1 doorbell". Is this what I think it is? Can we really switch off that awfull dingdong sound of the db1 itself?
Well I updated my IOS-EZVIZ app and I cannot find this switch. Has anyone found it ?
