Ok. It works on my iPhone. But do I need to reconnect it on my iPad?
Not clear on what you are asking, but I use the Wyze app on 3 iOS devices, sometimes simultaneously. An iPhone and two iPads.
You need to sign into the Wyze app on both devices with the same credentials, e.g. login name and password. Your cameras etc are specific to a login. For instance my wife uses my login on her phone to see the same cameras.
