This is some updated code that I’ve found recently that works a bit better.
|//The 100 value can be anything, Facebook will detect the height of the body element|
It can be triggered on load, or on an event. Theres no need for the setTimeout()… code any longer.
One the hard things about Facebook App development is debugging weird Facebook API issues.
Although hacky, this solution actually works.
|appId: 'APPID', // App ID|
|channelUrl: '//example.com/channel.html', // Channel File|
