The feedback suggests adding support for CancellationToken in all async functions to prevent race conditions when stopping and starting new operations. Specifically, the functions that need updating include MRUK.Instance.LoadSceneFromJsonString, MRUK.Instance.LoadSceneFromPrefab, MRUK.Instance.LoadSceneFromDevice, OVRAnchor.SaveSpacesAsync, OVRSpatialAnchor.SaveAnchorsAsync, OVRSpatialAnchor.LoadUnboundSharedAnchorsAsync, OVRSpatialAnchor.ShareAsync, and OVRSpatialAnchor.EraseAnchorsAsync. Currently, users are experiencing difficulties due to the lack of CancellationToken support, leading to the use of workarounds such as Mutex's to manage concurrent operations.
