I am testing IAP with sandbox enviornment, validating receipts (https://sandbox.itunes.apple.com/verifyReceipt)
However, few mintues ago, the sandbox server became unavilable, or, the response is very very very slow.
And I can't even make purchases of my app
As the image shows: https://i.imgur.com/pKkb4Ki.png
But the system status shows the iTunes sandbox service is available right now: https://developer.apple.com/system-status/
Am I the only one who are facing the issue?
