Gear VR Bug - app crashes after making a purchase if the Back button has previously been used

[edearl]

• Start app
• Hold the Back button until Oculus Home appears
• Select the "back" option to return to the app
• Make an in-app purchase
• Complete the purchase in the Oculus Store
• Expected: when the Store closes, the app resumes and continues working
• Actual: when the Store closes, the app immediately crashes and restarts

Reproduced in Unity 2017.2.0f2 with the VrBoardGame sample, on a Samsung Galaxy S7.

Is this a known issue? Is there a workaround or fix?

Best regards, Ed Earl
