Hi, I'm experiencing the exact same issue and wanted to share my findings in case it helps.

My setup:

Meta Quest 3 (4 devices)
Unity + Photon Fusion + MRUK Space Sharing
Meta XR All-in-One SDK v201.0.0
APK uploaded to Alpha channel, testers invited

My chronology: The app was working correctly, then stopped working spontaneously the following week without any changes on my side (no new build, no firmware update, no SDK update).

Phase 1 — First error:

ERROR_CLOUD_NO_PERMISSION_TO_MODIFY_SPATIAL_ENTITY GraphQL error code: 2128019 internal_anchor_uuid: 80569ce7-abaa-77c1-6aac-b8b013b0486a owner app id: com.oculus.guardian

Phase 2 — After factory reset:

ERROR_CLOUD_MESH_UPLOAD_FAILED GraphQL error code: 2128008 internal_anchor_uuid: beeb90ea-86ca-d629-37a5-263efa9e934a owner app id: com.oculus.guardian

Key observation from ADB logs: The upload of the app's own spatial anchor always succeeds. Only the Scene Anchors owned by com.oculus.guardian fail to upload. The code used is the standard room.ShareRoomAsync(groupUuid) as per official Meta documentation.

fb_traceids:

fb_traceid=EBvV8NP9m0d fb_traceid=DKZacnQLK4C fb_traceid=Fl5LV2uxHaJ

What I tried without success:

Cleared Physical Space History and redid Space Setup on all headsets
Factory reset on one headset
Reinstalled the app
Tested on 2 different WiFi networks and mobile hotspot
Uploaded APK to Alpha channel with testers invited

I notice at least 2 developers on this forum reported the same issue appearing this week. This strongly suggests a server-side breaking change or bug introduced by Meta recently, not a problem in our code.

Has anyone found a workaround? And can a Meta engineer please investigate using the fb_traceids above?

Hi, thanks for your reply,

Totally makes sense, since nothing looks wrong in my code, and even more strange that today I started with a fresh project [unity and meta], and getting the same error!

Getting this error on different devices, even the ones that never had the same app installed, so I think a factory reset also might not help! [will try it anyhow]

Do you also get this error in Logcat [I get it in some of the tries]:

Entitlement callback: isEntitled: True Name: MZ UserID: 0

have no idea why the user ID is 0!

It's been two days that I'm trying out anything [including what you mentioned], and it's still the same...

Hi, I just wanted to let you know that I'm having the same issue as you.

I tried everything you also did.

This strengthens the suspicion that there is something wrong on Meta's site.

I'm getting these errors:

SP:AF:AnchorFramework: operator() shareAnchorToGroup failed!
SP:AF:AnchorFramework: operator() shareAnchorToGroup result code: -400039
SP:AnchorResultCode: anchorResultCodeToXrResult: Unknown mapping for AnchorResultCode AnchorResultCode::ERROR_CLOUD_MESH_UPLOAD_FAILED(-400039)
[Error] Host failed to share rooms with group 63e6d4f5-19d1-7044-85f3-7dae1c22eb31 : FailureOperationFailed

Hi, yes, I also think there's a problem with cloud Meta.

I've opened a ticket and am waiting for a response.
