Issue is here:
Thought I would post here to bring more attention to it. Unity refuses to do an android build because of incorrect NDK version. It requires NDK 19.0.5232133.
If you try to download the NDK via the launcher, it downloads the wrong version.
If you try to download it via Googles website, you can only get NDK 19.2.5345600. There is no option to download 19.0.x
There is literally no way to perform an Android build and so it is impossible to test any new features on a real android device and provide feedback for the alpha.
