Hi, whenever I buy gems, I log in to AppStore after pressing purchase gems in castle story , it says continue to account info, then buy gems, it asks to confirm purchase in AppStore after putting credit card info, then press done. Then when I go back to castle story app, gems are never there at first, so I click on gems, click same as I bought- lets say $10 one, then it asks to confirm, and I press cancel. Straight after gems are there right away. Hope it helps
