I grabbed the following screenshot from a YT video:

As you can see the arrow right of "Sales" points down and you are able to access the menu by clicking on it.
However, in the fresh trial environment I recently installed the arrow points to the right and I'm not able to access any menu:

How can enable the menu so I can access the Settings of my Dynamics 365 environment?
As a former user of Dynamics CRM 8.x this is all very, very confusing. I can access apps, apps and more apps just about everywhere, but there isn't a basic navigation menu where I can access the entities and the systems settings? Wtf?
