When I try to open any of the Trimble Connect extension windows, the window appears, then immediately closes. The exact same thing happened to another user last year: Trimble cannot log in - #4 by workinghard
It seems related to credentials. I had to sign out of SketchUp (Help > Sign Out). Then I had to sign back in to SketchUp, and then when I tried to open Trimble Connect it prompted me with another window saying I had to sign in. So basically I had to sign in twice.
There seems to be a bug. Is Trimble Connect supposed to share the credentials from the SketchUp sign in? Or is it expected that you have to sign in twice? Either way, if the credentials fail, it should prompt the user, instead of just immediately closing the window without providing any indication of what went wrong.
