Really great to navigate app and love the way it works on my iPad. The biggest flaw is in the app you don’t have access to the notebook feature which you can get through your desk/laptop’s browser. I really love taking notes as I go through the lessons so I’m definitely missing that feature from the app; as well as starring my favorite lessons from a course. I like having the app because my iPad is more mobile and lets me take in lessons wherever I’m at, but right now I’m having to remember to log back in on my computer to star lessons & take notes which is a bummer. Developers please add the starred lessons & note taking 👏🏽
