I logged in with my microsoft account. This microsoft account is linked to my mojang account, but it says "play demo" and in windows edition and dungeons, it says buy now.

What I expected to happen was...:
that I logged in with my account, and that I would be able of playing the games.

What actually happened was...:
The old launcher was working properly, it told me to update, and I updated it.
For java, it says play demo, but it actually let me play the full game.
For windows, I can't play from the launcher, but I can play from the old windows 10 minecraft launcher.
For dungeons, I bought the hero's edition when dungeons was released, but now I can't play neither from the old dungeons launcher, or the new launcher.

Steps to Reproduce:
1. Log in with a microsoft account linked to an old mojang account, that microsoft account have to had bought minecraft java, windows 10 edition, and dungeons hero's edition
2. check if you're able of playing your games (in my case, I can't)

The following images shows the problem, and proves that I do have bought minecraft java/w10/dungeons hero's edition

The new and old launchers problem with java

prove that I have dungeons hero's edition Dungeons have the worst problem, I can't play from new neither old launcher

problem with windows 10 Prove that I have w10 (playing from old launcher)

I can't even log in with my mojang account, because I migrated it to microsoft.
