CATIA "Become a 3D Innovator Certificates"

Hello everybody, I am working myself into CATIA by using the Learning Modules for "Explore the Mechanical Designer Role". But I noticed that the turorials are outdated. And that was, because I was using the "3DEXPERIENCE rR2021x" version of the Learning Modules. Switching per dropdown menu to the "3DEXPERIENCE R2023x" version results in unaccessibility of the learning modules - please see the screenshot. Can somebody please explain how I can access the R2023x learning modues?

Another issue is, that the CATIA program started on my PC informs me to update it - see the other screenshot please. But I really can't find a way to do so? Is the sollution to reinstall the launcher?

Thanks in advance, 
Vincent
