I found similar issue. Not sure whether it's the same as yours or not. My video isn't display in Instagram.

TO FIX THIS
For my case, the reason was I didn't send backgroundResourcePath argument.
backgroundResourcePath mustn't be null so that the library will send the correct MEDIA_TYPE which is "video/*"

More information:
Video can only be set Background Layer (ref. https://developers.facebook.com/docs/instagram/sharing-to-stories)

ex.
await SocialShare.shareInstagramStory( imagePath: imagePath!, appId: '123', backgroundResourcePath: imagePath, );
