    Having same problem with Unity 2017.3.0f3. AssetBundle loads perfectly fine in Unity editor whenever I press Play button, but in both HoloLens Emulator and real HoloLens, no way of showing the Assets. It properly retrieves the AssetBundle from my web server, but then is unable to Instantiate my prefabs and GameObjects.

    Same issue here. I am unable to retrieve the content of an AssetBundle on Hololens, but everything is working fine on other platforms.
    Tested on Unity 2017.2.0f3
