Door view peephole cam intermittent door bell not working

Has anyone had the same problem as me with their door view / peephole cam?
I’m now on my 2nd replacement in 3 months and have the same problem every time
Basically 8 times out of 10 it works well but maybe once or twice a day when someone presses the bell it only rings outside and registers inside on my devices as a motion or person detected. It should register as an answered or missed ring. I’m starting to think it’s a common software fault rather than the device as surely when 3 devices do the same thing it can’t be the device. I have a great Wi-fi signal of -45 and everything else works well and the app is set up correctly. Any help or suggestions on anything else to try please? I reset the device, reloaded the apps and changed the ring cable on all three devices but no change. And it works 8 out of 10 of the time. I feel there is a intermittent software problem that ring are not aware of or they chose not to tell us about that intermittently doesn’t convert a motion when someone walks up to the front door to a answered or missed ring.
