Unreal Shared Spatial Anchor Sample

My team and I have been struggling to get this sample working. We have packagedthe project for the store and submitted a data use checkup so we have access to UserID and cloud storage. We have also downloaded our packaged build from the AppLab and are still not able to share anchors between 2 Quest Pro devices running on the same local network.

We're getting the following message in the device log:

13:10:22.826
OVRPlugin
[CreateSpaceUser] called for spaceUserId 0
13:10:22.826
Telemetry
[OpenXR_Anchor] userId cannot be 0;

OVRPlugin

Are we missing something that is not stated in the documentation?
