I&#x27;m surprised Facebook Chat still works for you?  My understanding (and others&#x27; experience, from a quick Google) is that XMPP Chat has been disabled since earlier this year: <a href="https:&#x2F;&#x2F;developers.facebook.com&#x2F;docs&#x2F;chat" rel="nofollow">https:&#x2F;&#x2F;developers.facebook.com&#x2F;docs&#x2F;chat</a>  They only supported exactly as long as they needed to to gain market share.<p>And Apple gets pretty much zero kudos from me for <i>client</i> XMPP support.  iMessage is a proprietary walled garden; client-only XMPP support is simply their one-way valve to get people <i>into</i> their network and only ever had any worth because Facebook and Google <i>used to</i> support XMPP.
