Got myself a GS-911 for my 2018 R1200RT, setup went fine, connected the device to my RT, and to the computer over USB cable.
I am getting a buffer index out of range error when running "AutoDiscovery"
Developers might have rushed the December version out to get started with their Christmas break :-)
I guess we are going to have to wait for them to fix the bugs after January 6th, oh well
