This website is so bad! I hate this website! They are so lazy in making an app, How did apple allow this trash! On PC, on the MS store it is also a website using Microsoft edge! Terrible website! The videos are outdated, and they are trying to make kids HATE school! The layout is bad, EVERY thing is Bad!!!! If nobody believes me then check the App Store reviews. That is all I have to say for this Trash company!
