Thanks for the reply, but maybe I need to be more specific.
I understand how live preview works, and it works perfectly for me on my school laptop > device as long as I'm not connected to the school network.
I can run live preview on my mobile hotspot and it will be fine, but as soon as I switch wifi connection over to the school hosted one and try to run it again, the session gets disconnected.
It sees the host, will connect, and tries to download, but the speed stays at 0 kbps until the host disconnects the other device.
Obviously, if I choose to roll-out C3 to my class (been using C2 for a few years now), this is one of the big features we'd be switching over for, so need to know if it will work beforehand.
