Motion alerts keep going silent on Android Phonet

Motion alerts worked flawlessly for several months until I put the doorbell on the actual door. Still worked fine until my wife and daughetr set up their (Apple) devices. Still worked fine until the next day when I would only get silent notifications. Dug into the settings and finally managed to re-enable the alerts, although I can’t remember where.Seems to only last several hours before going silent again. And then it takes me forever to find the dark-themed page that lets me re-enable the sound alerts. Today I can’t find it at all. Driving me crazy.And yes, BOTH modes, (at home and away) are set the same way, to enable motion detection. I went online and it says to use MENU and then ALARM ALERTS. I’m a reasonably intelligent person, but I don’t see anything labeled “MENU”, so I assume thats the “Hamburger” icon. But there’s No “Alarm Alerts” there.Please help. It really shouldn’t be this difficult.
