No Live View

I have two Ring Stand Up Cams that are used in my grandmother's apartment. For the past two weeks, neither camera will go into Live view and get stuck on "Activating Device." We have tried everything, resetting the router, turning the wifi on and off, turning the cameras on and off, disconnecting and then reconnecting the cameras to the Ring App. Nothing has worked. Honestly, at this point, I feel like we need to ask for a refund since the cameras aren't working and are therefore useless.Has anyone found a solution to this problem?
