Code working on Android but not in UWP

Description

The MediaElement and IndicatorView are working fine in the Android. But when you select the UWP in start up project. No video is playing. Also the IndicatorView is not scrolling.

I have this question on the StackOverflow, here is the link for reference. But someone said that this may be a bug in xamarin, so I decided to post this here.

Select the UWP in Start-up Projects.
Run the Source.
No video playing and the indicator view does not automatically scroll even if enabled.
