    The only way I was able to play the unity webgl video on an iPhone was using this browser: https://apps. apple. com/us/app/webxr-viewer/id1295998056 although I know this does not fix the real problem.

    Still not working on 2020.2.0b11. Tried both render texture, material rendering, far and near plane rendering.
