    Hi all,

    Running into an issue where when switching to the Front camera brings up the warning below -

    World tracking performance is being affected by resource constraints

    This continues until the app eventually crashes.

    I created a fresh project to make sure there wasn't anything else affecting it but getting the same results. Here is my setup -

    Unity 2019.4.20f
    AR Foundation 4.1.5
    ARKit XR Plugin 4.1.5
    ARKit Face Tracking 4.1.5
    XR Plugin Manager 4.0.1

    I've also tested AR versions - 4.1.3 and 4.1.7

    I'm switching the camera using a custom Camera Config script that is used in the AR Foundations Samples project. Then simply calling arCameraManager.requestedFacingDirection with either User or World.

    Anyone else running into this problem?

    Note from the team:

    This is a warning, not an error.

    This warning occurs when the app drops below the target FPS, which may occur on a configuration switch.
