I can't play Minecraft dungeons?

I bought Minecraft Dungeons yesterday and downloaded the launcher for it, but the launcher still contains pre-order (pre-order)

And when I'm on the Minecraft website and on my profile it actually says that I have it

It is only available from 11 a.m. Before that, nothing will happen

Oh thank you.

If I'm not mistaken, the game is a separate application that is not started via the launcher, but via the application itself.
