I paid but I don't see my credits in the app. What should I do?

When you buy credits for postcards, they should appear in your app immediately. If you don't see them, close the Mobile Postcard app, then reopen it. If you still don't see your new credits, log out then log back in. Check whether the payment was successful. And check that you are logged in with the same email address as you used to buy the credits. If you check everything and still don't see the credits in the app, contact customer service.
