First off, this package is absolutely wonderful. Great job! It works great if I use the emulator or sms but I've found a scenario where there seems to be a bug.
If I use Facebook messenger to issue the "command watch", I get the expected, "This channel/conversation is now where the requests are aggregated". Then if I use my cell phone, via sms, to request a "human" the process works great, asking to accept the conversation request. Then, after accepting, if I send messages from my cell phone (sms) those messages arrive just fine in Messenger but if I try to respond to the "client" from Messenger I receive:
"You said: hello
Type "command options" to see all command options.
Type "human" to initiate conversation with human agent."
Indicating the conversation is not connected.
