Sorry for the trouble! Your Pro is active through your Play account; Google sign-in is only for Drive backup and sync. On Google's permission screen the two Google Drive boxes start unticked: tick both (or "Select all"), then tap Continue. I've submitted an update that explains this in the app; it's under review now.
