You're quite welcome. Say, was your update also 36 GB, like mine?

I don't know about the Epic Games Store version, but if you are running the Microsost Store version, you have to click the 3 dots in the upper right corner of Microsoft Store and select "Downloads and Updates". Scroll down until you find the game and one of the columns will display the current installed version. In my case (see image) it's saying 1.1.387.0 If you are using the Xbox App for PC, it doesn't display the game version anywhere. But the app is just a wrapper for Microsoft Store that filters out apps that aren't games. Any installs and updates you make through the app are done by Microsoft Store in the background, so the same thing applies for checking out the version of the game.

What's the patch size on PC with Microsoft Store? It's downloading 36.3 GB for me. That's as much as the base game itself.
