When setting up the Facebook app, I get this error:
App domains must match the domain of the Secure Canvas URL, Mobile Site URL, Unity Binary URL, Site URL or Secure Page Tab URL. Please correct these domains: fb.com
There is absolutely nothing in your documentation about canvas, or creating this, another 2 hours wasted because your documentation omits important steps that mean that nothing works.
Very disappointed, please tell me what the answer is rather than just going in and doing it, I cannot believe the problems I'm having with this.
