We have an experience that uses arkit for vuforia using a marker. The app seems really inconsistent in picking up the marker when using ARKit, sometimes its fine and then others you cannot get it no matter what you do.
If we dont use ARKit and just use standard vuforia then it can detect without an issue.
We are only experiencing this problem on iOS, using Unity 2018.1.0f2 and Vuforia 7.1.35.
Any ideas what I can adjust to make it work?
