bought an app a couple of years ago; now it's unavailable in my downloads, App Store suggests that I pay for it again
hello! I bought a game called Elder Sign: Omens HD and made a couple of in-app purchases in 2014; then I deleted it because I needed space on my old iPad. now I'm unable to download it on my new one, because it seems like I've never bought it; App Store suggests that I pay for it again. the only proof that I actually used to own this app is a receipt (I no longer use this credit card though, but Apple ID is the same) and a ticket from customer support (I contacted them because I made an in-app purchase and was charged for it, but it never appeared in the game). is there anything I can do to fix this problem and download it again?
