It is a very educative piece. I love the breaking down of broad topics and how you summarise it for better understanding. The down side to the latest upgrade is the "offline exception". The previous version, one can go through it without the need for internet connection but now it's not possible. Please bring back that golden upper hand you had. It helps alot . Thanks

You use to be such a useful app. Now you just suck balls. And you're just getting worse and worse. Are you trying to strong arm people into paying for this app? I can't read any new updates cause it just says "problem loading" and "go offline"
