Make sure you have the latest US update installed. Remember that MSFS is in it´s most early Infancy. It still has to go through some years for it to be a mature product, just like other known flight sims have gone through in the past. That being said, personally I think it has quite alot to offer being in such a early stage, and what the community is doing with mods to get those default AC´s to high standards is quite impressive if you ask me, if you compare to how default AC´s are in the most common civil flight sims that are more mature out today.

Specifically with respect to Notre Dame, what are you expecting to see? It was subject to a massive fire in 2019. They only just finished removing all the scaffolding melted in the fire in November 2020. Recontruction was not scheduled until early 2021. Are you expecting a full representation of what it looked like before the fire? A burned out hulk?

Well the Houses Of Parliament in London look like what the tourist expect to see but IRL their covered in scaffolding ATM

I didn't 'expect' anything. But I did expect something. I was actually mostly curious how they'd handled it. Given the fact that what we see comes from the internet, I was hoping that we might be able to follow the repairs. Not every day, obviously. But maybe update it once a month or when significant progress has been made to the exterior.
