I got the window shopping achievement. (though I'm not sure why or how.)
Seems, as you say, that you have to visit the in-game store to get that.
I don't recall doing that, but guess I must have clicked on it out of curiosity at some point in time.
Maybe try visiting the store again and having a bit of a click about. It may register if you try again. Never know.

You have to set the game language to English to excess the store. since you seem to be from Austria you might run your game in German. Change to English and now you can enter the store and get the achievement.

Nope, I'm already running the game in English. Must be something else, but thanks anyway

Did you find a solution?

Nah, sorta gave up. Still not the slightest clue why it won't trigger

For me this worked:
1. Load into a save.
2. Click in the FM button to show various options.
3. Press Downloads.

Did you find a solution?

No. Gave up in 2022
