Paid on Play & now have to pay on Amazon too?

I purchased a license in the play store for my phone to use with my Spark. I want to use it on my Phantom 4 Pro screen as well but it seems the only way I can get it is through the Amazon app store which means having to buy it again. I would like to know how to get it licensed on my P4P screen without buying it again. Thank you

You will have to purchase it again. We’ve all done it if needed.
