Create sandbox will not come up after joining developer platform

Hi!

I want to lern more about MS 365 by learn-platform from Microsoft. So they wrote there, to sign up to developers network an get the free E5 license for learning purposes. 

So i signed up, everything works as written everywhere, but after the "3 forms to fill out", when it switches to the dashboard, nothing more happes.

Everywhere i have looked on videos (tutorials) then there should come up a screen to create (choose between the 2 options) the sandbox. But this does not happen here.

I also have received the welcome-message, where they also say that the next step is to add a new subscription on the dashboard, to set up a sandbox. But it is not possible/shown.

I will show you a screenshot of what i will get/see.

Hope that someone can help me, because at MS support chat, they could not. They told me 2 times that i will get a callback from someone who is responsible, but nothing happened... 😞
