IOS Safari Video Player with Sound: How to start play without an error? After bug fix 2020.3.16

We are trying to get the VideoPlayer working on iOS Safari after the bug fix in 2020.3.16:
https://issuetracker.unity3d.com/issues/webgl-ios-video-is-not-playing-on-ios

So far, video plays when muted. If we start play on an unmuted video with a Unity button (sprite with on click event attached that calls video.play()), this causes the Safari javacript error "NotAllowsError ... user denied permission. play@[native code] _JS_Video_Play. Note: we do not autoplay, but only play after pressing a Unity button.

The same build plays video on desktop browsers including Safari and Android Chrome, etc.

Is there a way to trigger a video with sound from a button press in Unity that will work in iOS Safari? Any other workarounds?

Thanks, Vinod

 

There's my asset.

 

Thanks @Marks4, will check it out. We would prefer a single solution for our three target platforms (WebGL, iOS, Android apps) which the native video player handles (except for Safari). Note: I've also had issues with Desktop Safari playing the video -- Apple keeps changing things!

On a related note: does your asset allow closed captions or subtitles to show in the video for accessibility? From what I understand Unity video player does not support this, a requirement for many use cases.
