Dont start any 3rd party programs until you are at the main screen…Just start the sim and wait til you get to the menu then you can load your other software
im unclear what ‘mystery update’ your referring too
we had 2 updates last week, on thursday we had the delayed WU number 8 listed here
then 1-2 days later? (location dependent) we had a Dev update shown here
admittedly the dates dont line up exactly, since the first update was delayed
is this on pc?
its tagged as xbox but that looks like a pc monitor, possibly used for a console?
