From times to times I get a very annoying dialog with the text: \"Tap continue and sign in to check for downloads.\" If I login ( with a sandbox user ) or tap Cancel the dialog
Sandbox many a times issues redundant dialogs which are not available with non-sandbox accounts. If you are following the storekit protocol there should be no need to worry. I had the same issue of repeated alert boxes issued from didReceiveResponse delegate, but my app got approved and it doesn't have issues in real environment.
