I am testing a Gear VR alpha build developed on Unity 2018.2.20f1 using the Oculus Integration 1.36.
I am using the credit cards mentioned for testing IAP items via a test user.
Purchase an IAP item (Consumable or Durable), is purchased successfully if using the 'Always succeeds' card or purchase fails on using the 'Always Fails' test card but both operations return via the LaunchCheckoutFlow Callback.
Attempt to purchase any other IAP item similar to point 1. The Oculus home is loaded with the loading animation displayed and then abruptly returns back to the game without any purchase. The Oculus.Platform.IAP.LaunchCheckoutFlow callback is not called in the process so it is stuck on the game loading screen.
The above happens if an 'always succeeds' test credit card is used.
If an 'always fails' test credit card is used the same happens but instead of the Oculus Home loading animation that can be seen for a while the number pad from the previous purchase attempt can be seen for maybe a second before the app loads back into the game window without calling the LaunchCheckoutFlow Callback similar to the 'Always Succeeds' card test.
I have used leaderboards, achievements, pricelist retrieval etc and all seem to be working fine.
The checkout code is as follows, however, the callback 'LaunchCheckoutFlowCallback_COINS' is not called on the second purchase.
