I just upgraded to a Moto Z Play from a Moto X 2013. At work, the firewall is pretty strict, but I did get them to open port 8883 over TCP (MQTT) for Messaging. Since then, the RW App notification on my Moto X 2013 has always said “Cell calls, WiFi messages & data”.
With my Moto Z Play, the RW App notification says “Calls & messages over cell, WiFi data”. I checked port 8883 using portquiz.net, and I can access it no problem, so the port is not being blocked. Is this a 3.0 vs 2.0 thing, or is there a bug in the 3.0 RW App where it’s not routing messages over WiFi when it should be?
