How to purchase from MAS with two cards?
I currently live in Venezuela but I have an US debit card. I have made all my purchases since 2009~ with my Venezuelan card, but now I will need to use my US card for purchases.
I purchased an app, and now the only app I have under purchases is that one. I have lost the dozens of apps I have purchased before with my other card.
Now, if I change the card information back to Venezuela, I recover all the apps, except the last one.
So I cannot update, have update notifications, and anything else. They are all under the same account though.
What can I do to prevent this? Am I doomed and I need to change my CC details EVERY time I want to check for updates?
