Receiving push notifications to buy an app that's paid for
My husband purchased First Year and we have been using it on our iPad. We just set up Family Sharing so I could access it on my phone. I have been using it about a week and just got a message saying I only have 20 more free entries and need to upgrade to continue using it.
I have gone back into Purchases to confirm I opened it correctly, and it appears I did because I only have an option to open the app and it takes me to my current entry. Do you know what I am doing incorrectly?
