Maybe this has happened to someone else?  I buught an EZ-app loco from Amazon.  Set up a basic oval of track to try it.  It connects to the android app and the loco cab light comes on then goes off.  After that, nothing.  Can't turn light on with the app and loco doesn't move (or attempt to move) with throttle.

Likely unrelated: In the app, the firmware version shows as 0.0.  Seems odd.

Help?
