Hey.
If you just got switched on for the New UX Beta there is something you need to know before you get started...
There is a New security role that you will need to Create Apps and Pages - it's called "Page Builder".
You probably have no apps and are wondering how to create them...

You need to find your "Tenant Admin" user, that person can go in to "Administration" and set up all the Page Builders.

After you have set the Page Builder permissions when you go back to the New UX via the link we shared with you it should look like this... Notice the "Create an App" button.

Happy days!! 🤘👍
