Problem with video playback with iOS

Hello!

I had a rather annoying problem with video playback on mobile devices, in particular, with iOS

I have not changed, and use the following code snippet:

Handheld.PlayFullScreenMovie ("video.mp4", Color.black, FullScreenMovieControlMode.Full, FullScreenMovieScalingMode.AspectFill);

When compiling on Unity 5.0 or so (I do not remember exactly), I had the Done button in the upper left corner of the player. And now, when compiling Unity 5.3 on the button, no.

How it is possible to solve this problem, but to the insertion of a third-party player from the Asset Store?

iOS Version: 9.3.1

the right image iPad 5

googled “unity ios video no done” and it yielded

Well, thanks for the help.
In the near future I will try to patch.
