I don't know how many times this XMPP setting has caught me out over the years.
Can we be a bit proactive here so instead of the log being filled with runConcurrentThread 2 arguments (1 given) errors, the Harmony Plugin simply logs:
Enable XMPP from the Harmony phone app Settings Menu>Harmony Setup>Add/Edit Devices & Activities>Remote & Hub>Disable XMPP>Cancel (to enable)
Great plugin by the way.
Thank you
