The 1 star is for the app. Not the instructors. The app just doesn't allow me to download the courses I bought. Every time I download the app will crash. We need better options for downloading other than mobile devices. Some courses take up 70gb of space. Much better suited for PC downloading. Allow us a desktop app. Update, I have emailed support and got told there is nothing they can do. Its a damn shame they don't care to fix the issue!
