After upgrading to V12.1, I had to upgrade the VBR console on our jump host, which is a terminal server.
I know that I have to close all consoles before upgrading the VBR, but today my coworker did not close the console (and I did not check it properly).
I then started the console and connected to VBR, I expected the "upgrade the console now" dialog to appear. But it just did nothing and said "establishing connection".
After logging all other users off the server, the upgrade of the console did work automatically.
It is no big deal, but it would be nice if the console upgrade had a check function in it that checks if other consoles are open.
Just a suggestion
