Two seemingly similar options you encounter are My Training, and Courses. when you are using the navigation bar and hover over the Training option, both of these will appear below it, and it is important to select the correct one to find what you are a looking for.
The My Training option will take you a screen that has all of the courses, curricula, and events that have enrolled in or that have been assigned to you. As you see below, this screen defaults to showing you My Courses (Underlined in blue), but there are two other groups you can use to view your enrolled or assigned content. Selecting My Curricula (underlined in red) or My Events (underlined in yellow) will bring up those groups.
The Courses option will take you to a page that has the entire course catalogue for your academy. Here you can search through all available courses, if you are a regular user, you will only be able to see courses that are listed as Public or ones that have been assigned to you. You can use the various filters as well to make sure you find the course you are looking for!
