Since Instagram has just launched the Reels feature I'm not surprised that Later hasn't caught up to the cover that is displayed in the Instagram Grid if the user chooses to share it there. It would be helpful if Later's 'preview' feature showed the Reels which had been shared. I haven't uploaded any IGTV videos with snippets on the IG Grid but if this is a problem for all video covers it's something that Later should resolve soon as Instagram is integrating more video content into their platform.
