Maybe this is just an android thing but it IS wide spread. I have RIng doorbell and Arlo, all motion notifications wake the device from a sleep and notify RIGHT AWAY no matter what.
Wyze alerts mostly only work once you manually open the screen or if you are already using the phone. There has been posts about this for months and months yet nothing. I even just tried the new firmware and WYze Beta app and still the same issue, even with the paid cloud storage service. This is a deal breaker and I will have to use my other cameras for motion alerts. Sigh. This is a wyze issue and not android 9 or 10 or 8 or 7 or 6 or 5
