Saying I Paid but won't work – Face Swap - Funny Photo Face change editor Review

Tried to pay $4.99 for everything (app and all in-app purchases) it says I already paid (which I did), but then it won't verify the receipt. Paraphrasing but this is the general gist of what happens: App says: "You have already purchased this item. Would you like to download for free?" I say: "Yes" App says: "Purchase successful. You're all set!" I say: "Ok" App says: "Verify receipt failed." Same thing happens if I try to purchase one pack (individual packs, as opposed to the bundle).
