Nice app, for a short while. I can't stay continuously logged in (kids), so I log in each morning, and log out when the kids return from school. Today though, I clicked the button to receive the 6-digit pin, typed it into the Messaging app on my PC, and got a message saying invalid PIN. I had typed it correctly. Tried 4 more times. Tried a reboot and tried again. No luck. UNINSTALL.
