Android App

I installed the app on both my phone (Nexus 6) and tablet (Nexus 9), both devices running latest version of Marshmallow. On each device when I try to open the app, I get an error message that says "Authentication for this app failed. Please make sure you have an internet connection". Then the app force closes about five seconds later. I've sent error feedback to Google. Any idea what might be going on?

Did you deny it access to the telephony permission? It needs access to your device's IMEI number to authenticate the app (it's used for upgrade purposes--I explained what it's used for in depth in another thread).
