Q: I keep getting a message that my account is not valid in the U.S. store and I need to switch to the Canadian store.  I do live in Canada.  How do I switch to the Canadian App Store?

Follow this procedure:

1. Go to Settings > iTunes & App Stores > Apple ID.

2. Tap your Apple ID

3. Tap View Apple ID

4. Enter your password

5. Go to Country/Region in the popup window to change to the desired store.

Many thanks for the advice. I ALSO found that I had to update my billing information.

Hi,

I had not had this problem before I changed to the new IOS.

I had followed the steps described, however it worked only once. If I'd like to download a new app 30min later, for instance, the same error message appears and I need to redo the steps again.

Is there a way to solve this problem?

Cheers,

Priscila
