    Hello!

    I'm getting a huge spike over 15 frames every time I start/enable the ARsession component.

    In the screenshot, you can see the spike and it's caused by the ARSession.Update() function (its taking 66ms)

    Is there a way to avoid that spike? To start the ARsession async?

    Some insight from the team:

    On Android, starting a session is a synchronous and expensive operation.

    Definitely what I'm experiencing! Is there a way to get a callback when the session has started? Or to start the session async?

    Thanks
