  1. Resolution Note (fix version 5.0.0-pre.12):

    Fixed in 5.0.0-pre.12

    To address this issue, we have added API that cancels existing requests, so that re-requests can be made which will be shipped with 5.0.0 of ARFoundation.
    If users wanted to handle permission requesting on their own. Canceling permissions could be handled the following way:

    void OnApplicationPause(bool pauseStatus)
    //Logic while paused.
