I am not a programmer but through some awesome youtube videos I installed Unity and actually made an AR app with my son for a project (for a history class, AR is just us goofing around).

So everything is working perfectly on the PC. We have an image target that displays an MP4 video i setup as a quad when it is detected. I used xcode to put it on an ipad. It started sorta working once I figured out how to give the app permission to use the camera. The issue I am having is it detects the target image but displays a grey box once it is detected, not the MP4 file. Does the same thing when it is supposed to display a jpg. Iany suggestions on what I need to try next to fix this? I am wondering if this is a permission issue or did the displayed files not upload?
