Of course it is, but that doesn't matter to a player who owns the game because microsoft say "Play anywhere" and "Crossplay" on their official marketing materials [0]
> Minecraft is inherently different here because they went for a re-write and chose to have two different "editions" of the game.
It doesn't really matter _why_, the fact is that it's the reality of being on an open platform that doesn't enforce these criteria. Being on a console you have to play by the rules of the platform which means that a bunch of things "just work", and those rules _mostly_ apply on PC, except when they don't.

The AOE2 one, sure. F1 2019 doesn't work between the MS store and Steam still. That doesn't change the fact that these issues exist on PC, and they don't on console.
