Question: How do I properly find out if my user did buy an non-consumable IAP after an App-Update

[georgbachmann]

Hello,
currently I am checking the IAP based on the Bundle-Receipt.
I do this with the following lines:

RMStoreAppReceiptVerificator *verificator = [[RMStoreAppReceiptVerificator alloc] init];
BOOL isValidReceipt = [verificator verifyAppReceipt];
if (isValidReceipt)
{
    isProVersion = [[RMAppReceipt bundleReceipt] containsInAppPurchaseOfProductIdentifier:<my identifier here>];
}

In general that works fine. But after updating my app in the app store I sometimes have users complaining that they are not PRO any more...
And I don't really know why... is the receipt maybe corrupt after an app-update? And if so, why?
Can I somehow find that out and refresh the receipt...? But then everybody would see the Please enter your iTunes credentials input box, right? And I'd of course like to prevent that... Cause somebody who didn't buy my product should not be bothered with that dialog...

It's so hard to test that problem as it only happens on app store updates and only for some of my users...

Any help is very much appreciated!!!!
Thanks

If you close it, you should also comment on the other one as it seems a major problem that I think a lot more people are suffering with.

I already did :)

Can I close it or do you have to close it? I can't find a button to close it...

I don't see a close button either.
