New Version Minecraft Installed - "you don't have a license for Minecraft"

I purchased Minecraft on the Google Play store (couple years ago). My boys have been able to download, install, and play Minecraft as they are "members" of my family library.

My son installed (well, the app auto-installed) the new version of Minecraft a couple days ago and now he is getting the following error message:

It appears you don't have a license for Minecraft. Make sure you have downloaded and installed Minecraft from the store

I have uninstalled and reinstalled the program many times from the Play Store and I keep getting this message.
