    Hello,
    When I use unity2020 build for Hololens, the WorldManager.state is always "Unavailable". I have set the XR Plug-in Management like this:
    upload_2020-10-13_15-14-33.png

    And it works well on Unity2019.3. The state is Active, then I can start my process.
    I alse notice this:
    upload_2020-10-13_15-17-50.png

    Dose this means the "state" is unuseful? So how can I get the Hololens world state?

    WorldManager is part of the Legacy VR API that was deprecated in 2019.3 and removed in 2020. What is it you need from the world state specifically?

    My Process is
    1. start app
    2. check state
    3. if state is active, then set anchor position, and the next action; if state is unavailable, stop and return;

    So I need to known current world state. Is there anything replace "World.state"?
