This happened with one of the 3.1 updates also, not sure if the symptoms were exactly the same, for that one I uninstalled and reinstalled the app which fixed it, this time I noticed that it was just a setting in the android settings that toggled off.
All notifications stopped after the 3.2 update happened this morning. Events still logged. When looking in Android 14’s settings under notifications for wyze, had to drill into the “Wyzenotification” one and within that, there is a toggle for “pop up on screen” that was toggled off. So if your notifications have stopped working, check there.
