Doesn't seem to be quite working?

It sees my account and verifies credentials ok, it can see my list of conversations but just sits spinning the wheel and not doing anything if I try to load a conversation and seems currently to have no way to begin a conversation.

Based on previous threads here, I'm assuming this is the result of updates at the FB end, which is fine - if you're hooking an app into someone elses' system then from time to time it will be broken by updates beyond dev control. Is there any idea of a time to fix, please?
