....are you referring to the App Store application in OS X where you can purchase and download applications for your Mac, or are you referring to the App Store in iTunes where you can buy apps for the iPhone and iPad?
I clicked on App Store under the black apple on the menu bar. I assume it's connected to iTunes as it had a monetary credit equal to what I have in my iTunes account.
I don't have an answer to your dilemma but I think you can get help for your problem in the Apple Express Lane
. I will be interested to hear what you find.
I found that they don't care to answer the question. After I described the problem I concluded with: ""As I haven't done anything different and didn't even know there were two stores .....what do I do?"
They asked for more information which I provided in detail, with a click-by-click description of the events and exact wording of the dialogue box.
The next response was:"Glad to hear from you again. App Store Support person name, here with iTunes Support. Hope your day is going great so far. Thanks for your reply. I know making new purchases can be exciting, and how frustrating it is when something like this gets in the way.
Perhaps the iTunes Store on your desktop/device that you are trying to purchase on, the country listed is the US. Since your account is Canadian you will only be able to purchase from the Canadian Tunes Store. You receive that message when a noter (sic) country is listed on your desktop/device.
My Name, I will always be an email away if you ever need help in the future. I know things can get confusing sometimes and it's always nice for assistance. Enjoy the rest of your day."
It appears they thought that the problem would be magically resolved if they just told me what I already knew.
Fortunately, this story has a happy ending. I went into the iPad Settings. I turned both "Apps" (under Automatic Downloads) and "iTunes Match" on and off, leaving them both in the off position. Things now work as they did before.
So, while I can't thank Apple for any real assistance, I can at least appreciate the comic relief they provided.
