With at least unity 2021.3.6, OpenXR with mixedreality openxr 1.10 and worldlockingtools 1.5.9 and master, compiled in UWP64 for hololens 2.
The persistance of the anchor does not work, and WorldLockingManager.GetInstance().AnchorManager.SupportsPersistence is false
To make it works, simply change the line 225 of file WorldLocking.Core/Scripts/XR/AnchorManagerXR.cs
from :
openXRPersistence = XRGeneralSettings.Instance.Manager.activeLoader.name.StartsWith("Open XR");
to:
openXRPersistence = XRGeneralSettings.Instance.Manager.activeLoader.name.StartsWith("OpenXR");
(juste remove a space !!!)
The effective name of activeLoader is OpenXRLoader as shown in logs :
ActiveLoader name:[OpenXRLoader] type:[UnityEngine.XR.OpenXR.OpenXRLoader]

It will be great if this can be corrected in the master !!!
