Steam tracking doesn't work with Virtual Camera (Unreal Remote 2 app)

I tried in version 4.24, but found on the forum that it’s an issue since 4.20.

Whenever I run streaming to an iPad app, the steam tracking (vive controller, vive headset) just stops tracking. It’s ok until the app connects to the editor.

How can we stream tracked camera to iPad using vive tracking and not ARKit?
