Great app but bugs – Marlee Signs Review

I love this app but after a while the screens were turning black and I could no longer access some packages so I decide to look at the comments and multiple people are having this problem too and then I saw that if you deleted the app and then restored your purchases it would fix the bug. So I decided to try that and when I restored the purchases it said no purchases were found?! And I really loved learning this app but now I don't have access to all the purchases I had bought before. Please help!
