Bug AR Foundation - marker never picks up on first scan

This ONLY happens in Android.
Static markers seem to work much better than dynamic ones.
Does anyone know why this might be the case?

What could I be doing wrong with dynamic marker loading that might cause the markers to not pick up when the app first boots?

Code (CSharp):

1. IEnumerator ScheduleSetupTrackedImageManager(){
2.     while(ARSession.state < ARSessionState.SessionInitializing) yield return null;
3.     var runtimelib = trackedImageManager.CreateRuntimeLibrary();
4.     var mutlib = runtimelib as MutableRuntimeReferenceImageLibrary;
5.     Unity.Jobs.JobHandle handle = mutlib.ScheduleAddImageJob(markerTexture, markerTexture.name, markerTextureWidth);
6.     while(!handle.IsCompleted) yield return null;
7.     SetupTrackedImageManager(mutlib);
8.   }

In my experience, the mutable reference image library works unreliably with ARCore 4.0.x. Please try to update the ARCore to 3.x.x or ARCore 4.1.x.

 

Thanks so much @KirillKuzyk . It really appears from a cursory read that this is indeed the problem. We'll investigate more deeply tomorrow.
