I have placed into a layout a container field formatted to "Optimize for Interactive content". When I upload a video to that field, it renders perfectly from FMP. I can see the first photogram of it and all the buttons to control the display. However, when I open the same layout from FMG it is just shown the icon instead of the photogram. Is it the expected behaviour in FMG? I do not like to see just the icon in the middle of the container field in FMG. It would be a much better user experience to see the same than from FMP.
In case of that is the expected behaviour (as I suppose...) is there any advice to show container fields with video in FMG?
