I bump this topic (I don't want to make a another similar topic) After the 132, the Instant game facebook doesn't show up anymore the canvas. It freeze in the loading showing the error in the screnshot.
To make this bug, just make a empty project, add a text and the instant game plugin and export the file with no minify. On start layout, set text from the ID of the instant game user. (the same project, exported with the 131 works)
Looks like a strange bug anyway.
