Vuforia 9.8.11

could you explain how to reproduce the issue.

I tested with Vuforia Core Examples with 9.8.11

There we have the scene 3-VuMarks in the folder Assets/SamplesResources/Scenes 

When open the scene we can see the VuMarkHandler object which has component  VuMarkHandler.cs script. The VuMarkHandler uses the VuMarkManager according to


e.g. when we check the code we can see


void OnVuforiaStarted()


        // register callbacks to VuMark Manager

        this.vumarkManager = TrackerManager.Instance.GetStateManager().GetVuMarkManager();




        this.vuforiaCamera = VuforiaBehaviour.Instance.GetComponent<Camera>();



Testing the scene was working fine - so means the VuMarkManger was working fine in 9.8.11. How did you detect that it was not working? Could you , please, verify with the Vuforia Core Samples? Thanks!
