after moving to Unity 2017.4.2f2, when I build my app for Android, the screen is black on all scenes using AR.
It is ok in the Editor.
I am on PC.
I have seen a few post regarding this issue but none solved my problem.
I don't know if this is related to Vuforia or the build itself, but I have also a QR code scanner in the app that ceased to function too
Help greatly appreciated as I have a demo soon (I am in trouble).
Many thanks in advance.
