How to share my purchase with my family?
You can now share all your Genius Scan purchases with your family (in-app and apps purchases).
Unfortunately, due to Google Play restrictions, it's not possible to add Genius Scan+ to your family library if you purchased it as an in-app purchase in the free app Genius Scan.
You can request a refund for this purchase as described here: Get a refund on Google Play. You can then purchase Genius Scan+ directly on Google Play, which you will be able to add to your Family Library.
