VideoPlayer is not playing on WebGL on mobile

I have a WebGL project that works great on Desktop and Mobile browsers. Besides one thing, on Desktop the VideoPlayer's video from URL plays fine, on Mobile the VideoPlayer's video it downloads the video but only displays the first frame of the video.

I am also preparing and checking that it isPrepared to call Play.

     videoPlayer.Prepare();
     while (!videoPlayer.isPrepared)
     {
         yield return new WaitForSeconds(1);
     }
     videoPlayer.Play();
