We are experiencing widespread issues (on all versions of iOS) with Testflight In-App purchases failing. Purchases are working as expected in Sandbox environment with Sandbox testers created in iTunes Connect.
Normally what used to happen is that we could send a build to our Testflight group and they could use a production App Store account to make purchases (The Apple prompt already says that the purchase is in Beta and they will not be charged. However, now whats happening is the purchase fails with a "Cannot connect to iTunes" error.
To confirm, the SKProducts are loaded perfectly, even a Restore purchase seems to work. Its just buying anything that fails.
We have tested using a Sandbox account in TestFlight and this actually works which is not what we expect since Sandbox testers shouldnt work in Testflight?
Anyone else experiencing this
