ZAFClient.init() throws timeout exception

Hi, I have this app that after processing the OAuth callback it redirects to itself in the Zendesk zendesk iframe.

The problem that I am seeing is that the ZAFClient.init() throws a an exception due to timeout which I am assuming is due to app.registered event not being triggered.

My question is, is there a way to reload the app to better handle this cases? And when does the app.registered event gets published?
