I have installed several different models of Eufy cameras around our church. I have a Oneplus 8 phone that I have the app on. My problem is that receiving audio notifications is very intermittent, sometimes I get them, sometimes I don’t. I have gone through the settings following directions from Eufy’s site and other posts online, but have had no luck. Is it possible the problem is with my phone? It kind of defeats the purpose of the cameras if I don’t get notifications.
