It works … if you allow Location access
Updated review: this app does work, but only if you allow it to access tour location. Apparently it uses the WiFi SSID to decide which type of camera it is connecting to. Once it can do that, it will flip the correct one green (from grey) and you can tap it to open. It would be nice if this was explained somewhere, instead of just silently failing. Not specifically related to the app, but the tool in general … this thing is an exercise in frustration. It resets its wifi connection every minute or so, freezing your view until you can reconnect your phone. So just as you've gotten to something you were trying to look at, you'll lose your grip and have to redetermine camera rotation and get back to that same place, hopefully before the wifi resets again.
