I’ve also stopped receiving notifications on my v2 cam.
Nothing in the app has changed. Detection zone is set and when something moves in it, a notification is no longer sent out.
I’ve toggled the notification on/off in the camera and home page settings.
IOS notifications for Wyze are also all on.
I haven’t reset the camera yet but will try that next chance I get.
Support has been unhelpful and asked me to do everything I already told them I did before asking me to factory reset.
