I purchased Minecraft, but it is not appearing in my Google Play Family Library
In the Google Play Store app, navigate to My Apps & Games. Within the Minecraft details page, turn on Family Library.
I cannot launch Minecraft even though it is listed in my Family Library
Please make sure that each family device is signed up to the Family Library under the same Family group.
