What a complete rip-off – Masterly:Learn, Grow, Monetize Review

So I got this app and the growth workshop during a promotion. The only thing I could open was the Start Here, soon as I clicked on the first lesson all I got was the prompt to upgrade to premium. All the lessons crashed....but not the upgrade prompt? So I emailed them about it, and what was the response? Nothing. Useless.
