World Anchor Persistence
I have being working with the world anchor store, saving and retrieving world anchors for correct positioning of objects in the spatial mapped environment. But due to some reason when I remove all holograms from the SETTINGS > HOLOGRAMS > REMOVE ALL HOLOGRAMS panel of the Hololens, the application is not able to retrieve the world anchor when I run it.
Is it related to the world anchor being stored locally in the Hololens or should I go ahead with the Azure spatial anchors?
