Book sent as a gift can't be accepted - different App Store than mine
A dear friend of mine had a birthday and I decided to send him a digital book as a gift. The payment went through, but my friend wasn't able to receive the gift, because we're not in the same country anymore. But I didn't get an error message, although Apple should be absolutely aware if certain email is linked to certain App Store and they are not compatible with the sender's App Store.
I'm in Bulgaria he's in the US with the respected app stores.
Since I paid for the book, how do I at least get to read it myself, if he's not able to?
