All is in the title.
We have a project on Unity 5.6.1f1, we used to let Metal on for Graphical API and it used to work well. But since yesterday every time we start our app on an iPad Pro 12" using iOS 11 (the same that we used before and where the app worked) at the moment we enable vuforia the app freeze then the iPad reboot. on Xcode we got VideoBackgroundConfig size of zero.
We decided to use OpenGL es 3, now vuforia is working but when we get the targer with a VideoPlayer plane on it, the video freeze or lag very much.
Using Unity 5.6.1f1 on iPad Pro 12" Vuforia 6.2.10 with Metal Crash (But it used not to 5 days ago, and the video was clear and not laggy)
Using Unity 5.6.1f1 on iPad Pro 12" Vuforia 6.2.10 with OpenGL es 3 lead to video lag
Any help is welcome.
