Welcome to Austria, Germany and Switzerland
I feel I should start by saying that the update procedure Microsoft has adopted leaves a lot to be desired. Not for the first time, many users have had problems navigating through the complicated method of applying these updates and sadly, that includes yours truly.
I always wait a day before updating, to give the servers time to address those who wait with fingers hovering over their mouse buttons. Then it’s generally just a matter of launching the sim, where I’m told there’s an update available, followed by the Microsoft store which opens with a link to it. Yet this time the store didn’t show one.
