    It's still not working for me! All I am doing is using the built in Video Player with no scripts . I use URL link it to https://files.myfilesehsekjfb and in unity, bud does not work on ITCH.IO!!! OMG This is so frustrating!

    I am not good with code, i am on 2020.1.0b9 which supposedly fixes the issue!! What am I missing?

    @Bluesheep They say the fix will be included in 2020.1.0b9 and currently only 2020.1.0b9 is available, so you will have to wait a couple of days.
