It would seem that contentTitle, contentDescription etc have been deprecated when sharing via Facebook. I’m working on a game where i want to share information about the players progress, such as they just scored X points or they just collected such and such, without being able to dynamically specify the title and description this kills sharing functionality. Any ideas how to provide a link with custom title and description? Would I need to write a server script that returns a generated page with the OG tags that contain my custom title and description?
Found a way around it using my own php script, more details on my blog Facebook Share Dialog Borked! – DrMop
