To be more exact, it does not generate the correct index.html file.
When I upload de zip bundle:
Must Reference SDK via CDN
Games must reference one of our supported SDKs via our CDN.
have you even added the plugin?
Develop games in your browser. Powerful, performant & highly capable.
Not sure which plugin are you talking about.
I got it to work by adding a reference to the connect.facebook.net/en_US/fbinstant.6.3.js script.
to the index.html that gets generated inside the .zip bundle, not sure if this is a bug or is because I'm missing the plugin you mention.
Btw looks like I can't post html code, I get a "you've been blocked" screen from cloudflare.
Nvm. I've added the instant games object and then it works, without having to add anything.
I think it would be good UX if the Instant Games export option were disabled if the Instant Game plugin is not installed in the game.
This is already corrected, in R176.
