Bluebeam Revu needs a command line switch like /server:Germany, to preset the server, so that the Revu user does not get a server choice when logging in.
Literally all our customers need this. Since the introduction of release 21, we at IDEOMA have a constant job of making sure that people pick the right server, while computers can do that for us. Only recently we've wasted Bluebeam Support's precious time on moving one account's users from the UK server to the German server, because this customer had overlooked our instructions.
