WiFi blocking RCS messaging on IPhone

[Dave-XR500]

If you are still having problems with your XR500 and iPhone RCS chats, you can always disable the QoS (and reboot router after making the change) inside the XR500 if that is something you are okay with (like I was mentioning in my previous post). Something tied to QoS is blocking the connection with iPhone RCS, which is rather suprising. I tried everything else (port forwarding to appropriate ports, etc.) and that was the only solution that worked for my home network.  I have everything else still enabled in the router, except for QoS being disabled, and my wife's iPhone has worked perfectly with RCS chats (since disabling QoS on the XR500). I had to reboot router after disabling QoS then it works great.
