Thanks Allen, Got it!
Yes, it is just like the phone. My Google account shows I have several installs. I had to select the one for my Neutab and tab on it and found a new windows with the install option.
What was confusing is that the Play Store said it was already installed. Which it was, for other devices. So there is a drop down menu. After doing a double tap on
Neutab G7, it showed another install window.
Your suggestion made me look again in the play store.
