Doesn't "GARFrame.earth.cameraGeospatialTransform" get tracked if it's a virtual location?

[hina9]

Is "GARFrame.earth.cameraGeospatialTransform" not tracked if it is a virtual location?

I have completed code to generate anchors when the device's position is within a certain range, but when I tested it again a few months later, no anchors were generated.
I checked that the cameraGeospatialTransform data is not carrying my iPhone's (virtual) position as 0x0,

I tested and found that the tracking of garFrame?.earth?.trackingState was paused for the virtual location.

Is it correct that I can't use virtual location for earth?
