Media Projection is disabled on v44

We are developing VR device management system that can monitor VR viewers' screens.
we are implementing mirroring function using MediaProjection API, and it worked in v43.
However, after updating to v44 it was not working and we found the following log.
 
10-13 16:41:59.750  4070  4070 E MediaProjectionPermissionActivity: Screen recording via the Media Projection Manager is disabled; canceling operation
 
It seems to be happening in MediaProjectionManager.createScreenCaptureIntent().
The expected behavior is for a permission confirmation dialog to appear, but no dialog is displayed.
 
MediaProjection is not available in the future? Is there an alternative?
We are very troubled as we consider this an important feature.
 
We are unable to post the logs for our application, 
but were able to reproduce same log with the following mirriorg application.

    We have also tried v46 and encountered the same problem.

      Did you ever receive a response via zendesk? This issue seems to be there for a while now, so they'll probably have no intention on enabling media projection again?

        Currently I'm getting this on Quest 2 with v65:

        Similar problem on Quest 3:

        It seems like they have explicitly disabled the feature. Does anybody know of a way to enable it?

        We identified a device property named persist.device_config.oculus_shared_os_services.vros_enable_media_projection set to false. However, attempts to change this property to true have been unsuccessful.
