Ratings and reviews

This is an amazing app! I am satisfied as a casual learner because there is so much content to get a hold of. Such a great productivity app!

It is just stuck on the splash screen, I uninstalled it then installed it again but still not working. edit:the update is fantastic

Please I don't understand how it works. When I click on the problem part and I am given a question I don't seem to find a place to solve it especially the ones involving to write codes. Any feedback will be appreciated
