Hey guys, I am not asking a question because I have already fixed it. I am posting it here so that it can help anyone facing this issue.
Issue - Easy Ar was working perfectly on android but on IOS the camera feed was getting stuck and active objects were moving with the camera.
Fix: I had a small scroll view in left portion of my screen. The viewport was using a Mask with stencil material. This stencil material was causing the issue ( I have no clue why??). I replaced the mask with rect2d mask and deleted the mask, image, canvas renderer and stencil material.
Hope this help
Cheers,
