Handheld.PlayFullScreenMovie on Android 9?

I am trying to play an mp4 file with

Handheld.PlayFullScreenMovie(
            path,
            Color.black,
            FullScreenMovieControlMode.Minimal,
            FullScreenMovieScalingMode.AspectFit);

This runs ok on iOS and Android 7 but it sometimes does nothing on Android 9. At other times, it plays the video, but missing the first couple of seconds (The displayed video length is the correct one but the frames are not there). Any idea how I can fix this?

Anyone…?
