i have been having this same issue for the past few months. it worked at first when i would share on instagram, which was awesome, but all get is that same screen as you now. i wrote to support but never got a response.
i make so many brilliant moves! 
But i cant share them anymore... so whats the point...
Hey guys,
Just realised the share function from the game review screen isn't sharing moves like it used to, which I typically use to show my other low rated friends my Brilliant! moves 🤣
Instead of linking the game and showing a screenshot of the move in question, it shows a strange image of the chess.com application on a laptop and mobile phone.
Anyone had this issue and found a fix? I have a killer move I need to show!
