Gear Vr app not properly configured for S8 app rejection.

My app has been rejected from Oculus store because of:

“It appears that the app is no configured correctly to display VR on the S8. Everything looks off center and it looks like you’re seeing everything through a fisheye lens.”

As soon as I have no S8 to test this issue, I would like to ask if somebody have the same problem resolved and if so - how and what should I configure.

Unity v5.6.1f1, Oculus Utilities v1.15.0, OVRPlugin v1.14.1

Thanks in advance.

I have the same issuse, first I use 5.6.2p1 to submit, I got rejected because s7 and s8 got fisheyed HUD,
then I use 5.6.2p4, now S7 passed, and I have a quick look on s8 I cant observe wired UI again,
And I got failed in my second submission and only s8 failed, this time I only saw the big UI plane got fisheyed, which I havent checked before my second submission.
I think updating to Unity2017 will solve the problem, but It have bug while importing my psd file so I cant use it.
Need to wait another patch of Unity2017 before my third try.
