I Tried using the app today but after I open the app on my iPhone and iPad I get this really weird screen that says SMART TEST SETUP SCREEN on the top and for some reason it's not in the App Store anymore. I uninstalled the app on my iPhone and was going to reinstall but it seems to be gone from the App Store.
I've had the same thing happening to me on my iPhone. I did not remove the app, instead I went into the App Store and looked up my Verizon mobile app and it showed that it needed to be updated. I did just that and the app is working just fine again.
