You share the camera settings. If the camera has notifications enabled, you both the get them. If they are disabled, no one will get them. I was saying if you enable the notifications in the camera for you, then he can go into his app settings for iOS or Android and disable all his Wyze notifications, that will work. He won’t get any notifications, but you will get whatever the cameras that your have that have the notifications enabled.
There is a rather large wishlist that is about this, multiple shared user permissions. Visit and give it a vote!
