Hi,
I have added open graph meta tags to my website to leverage preview ( rich links) on IOS 10 for IMessages . Share works fine if the OG tags contain image / video . Where as if I am trying to have gif in "og:image" property with "og:type" property as "video.other" the preview on the IMessage ( on IOS 10 ) does not show gif rather shows just image ( I observed it shows first frame from GIF in the preview ) .
But this blog shows GIF preview working on IOS 10 : http://mashable.com/2016/07/10/apple-ios-10-gifs/#5BHGM.lN08qq .
