There are a few minor issues I have found with MFS2020, like the twitchiness of the controllers, problems with the drone camera controlling my elevator, etc.  I am sure these will get ironed out rather quickly.  The main issue I have is the triangular building blotches in the distance when approaching a city.  I have no issue with the building colour or lack of detail from distance but surely they can get the general shape correct so they don't all look like triangles.  I hope they can improve it.

Does increasing the Terrain Level Of Detail slider help? The triangular objects is what photogrammetry areas look like at a lower LOD.

I will give it a try.  I think I am 100 now but noticed a big performance hit when raising up too high.
