Greetings,
The R6 mkII should basically be the same as your other body's. I would suggest deleting the camera profile in the Canon Connect app if one exists and performing a network settings (only) reset on the body. Then perform the pairing operation again.
There are basically two ways to connect. One is ad hoc with the camera acting as the host access point, your phone connects directly to it. This is the method I use most often.
The second is connecting your camera and mobile device to the same wireless network. Then opening the CC App to complete connection.
When you use the ad hoc method, it's important that you confirm the camera is broadcasting it's SSID and password. You then open settings, network and Internet on your mobile device, select and connect to the camera's broadcast by tapping on its SSID name and entering its password. It will show as connected, no internet. You then open the Canon Connect App to complete the connection. Hopefully this helps.
