Why are past purchases no longer showing after I change country of my Apple ID?
This is by design.

A developer lists an app for one or more markets and when you lose past purchases, that indicates that that app was available in the old market and no longer is available in the new market.

Have a look on the site, there are several threads on people deciding to switch countries or keep an old account.

One is simpler and potentially costs more, the other costs more time, but you keep access to all purchases, past, present and future on two accounts.


I want to change the country on my app store account and I am having some problems?
Restoring past purchases from different country
Do I need to repurchase apps if I moved countries?


Also - the related section to the right should have several more likely threads to help.
