Spatial Anchor pose becomes "stuck" and fails to update after device sleep/wake or tracking loss.
I am experiencing a critical issue with Spatial Anchors in my Unity application. When the headset goes to sleep (e.g., by accidentally pressing the power button) or when tracking is temporarily lost (e.g., lights turn off, covering the cameras), the anchor’s pose becomes "stuck" in the last known position/orientation relative to the headset (or the last known coordinate space).
Upon waking the device or when tracking resumes (lights turn back on), the anchor does not update its pose to its correct real-world location. It remains locked in the wrong position, essentially frozen in the virtual space relative to the user, rather than staying locked to the physical world. The anchor’s pose only corrects itself if the application is fully restarted and it has been loaded again.
I am using Quest3 on v81. Does it need persistent tracking throughout whole session to track anchor? Is there any way to force it to re-localize existing anchor without loading it from shared group again?
