I am testing a new iOS app which has an in app purchase, and I am getting some unusual behavior when testing the app through Testflight.
When the app is launched, I perform local receipt validation to determine if the in app purchase is in the receipt. If no receipt, which seems to often be the case in testflight, I make an skreceiptrefresh request, as recommended in the receipt validation guide. This results in a user prompt to enter app store credentials (even though signed in), which is annoying but acceptable. I then process the receipt when it returns in the requestDidFinish delegate method.
However I am seeing some odd behavior which I believe is related. I download and run the beta app via Testflight, and enter the app store credentials. After this, I close the app. If I then swipe over to the iOS search page, I am prompted to enter app store credentials, even though logged into the app store in the iOS settings. This only happens once, but if I delete and reinstall the beta app, it will recur.
Has anyone seen this behavior? Is it a Testflight bug? Could this somehow be related to the skreceiptrefresh request?
