  1. Resolution Note (fix version 2021.2):

    AssetBundle.Unload will wait for all asset bundle async operations (for example LoadAssetAsync) to be completed before proceeding. Also logs a warning when this scenario occurs.

  2. Resolution Note (fix version 2020.3):

    Fixed in 2020.3.23f1

  3. Resolution Note (fix version 2019.4):

    Fixed in 2019.4.33f1
