OS v76 Has Stopped 'Tracking Origin Type: Stage' From Working Correctly In Roomscale

Question

Since headsets have updated to OS v76 my apps can now be re-centred by the user. Previously while in stage mode it was not possible to re-center which is a requirement for my calibration. My headset on v72 does not have this issue. Have tried multiple versions of the SDK including v76.

When building from Unity using 'Build and Run' in the initial run the playspace cannot be re-centred however if I close the app and manually launch it can now be re-centred on all subsequent launches.

EDIT: Update on this, when in stationary mode I cannot re-center while in Stage mode. If I switch from stationary to roomscale while in the app still I can still not re-center. However if I quit the app and relaunch while in roomscale I can re-center again?

EDIT2: Another update, if you are not in passthrough mode before launching an app then this issue is fixed and you cannot recenter while in roomscale mode. So its an issue with there being no boundry before loading into an app which is now causing Stage mode to be broken and allowing recentering.

Does anybody know if this has this been solved in more recent updates?I'm still at v74 and don't dare to upgrade now...

In the v77 SDK just released, they introduced a new tracking mode called "STATIONARY" - they say to use it in place of STAGE for MR experiences. Not sure if it solves your issue or not, but thought I'd make you aware in case is does:Meta Developers&nbsp;- under "Whats New", second bullet.Heres my ChatGPT convo about it:https://chatgpt.com/share/684aeee7-0b78-8000-a4f0-065721260422

I don't believe STATIONARY mode is a solution for me but will give it a try. In my case I am setting a position in one app and that position gets saved to a backend and is pulled down by multiple different apps which is why I cannot use shared anchors and require no re-centering.

For now I am getting around the issue by continuing to keep the headsets in non-passthrough mode before launching apps.

I also noticed Stage Tracking stopped working. I use it with Virtual Desktop and Space Calibrator to allow full body tracking using the vive 3.0 trackers, and despite Stage Tracking being enabled, the headset now recenters the position each time it is temporarily taken up and back down to my face, having then to recalibrate the whole thing to align tracking. It is super annoying and definitely a feature they will need to fix!!!

Did you say that for niw there is a clunky work around to keep stage tracking enabled?
