Since I liked my tablet with Mobilesheets Pro so much, I convinced my church to buy a matching set of them for our ensemble to use. 

I just received four tablets in the mail, completely identical to the one I am currently using successfully...and all of them are telling me that "Your device isn't compatible with this version".

All of them are running Android 4.4.4, up to date as far as they'll go.

Please help resolve this...I don't want to send them all back!
