Please fix that issue!! thank you :)

I had the same issue on 2017.3.0f3 and Android (iOS works fine), and after trying a lot of things, what worked for me was to go to the end of the video (videoPlayer.time = clip.length), wait 1 sec, play the video, wait 1 sec, and then advance to the "rewind" position previously stored.
Without the waits, it just do the same error, "pause" the video and then play it after a couple of seconds/minutes

This problem fixed in Unity 2018.2.b8, but sometimes this problem happen again.

Fix confirmed:
float currentTime = (float)videoPlayer.time;
if (_time > currentTime)
videoPlayer.Pause();
else {
videoPlayer.Stop();
}

videoStatusText.text = "LOADING";
videoPlayer.time = _time;
videoPlayer.Play();

We have found a way to workaround this bug , we restart the url when we want to seek backwards , so the "backwards" is converted to "forwards" ; Another way is you can prepare two videoplayer , that can convert the "backwards" to "forwards" , too.
, by Sam and Rw from China, we hope this idea can help you.

Please fix that issue!!
