Do u need to pay to start or what..???Ty

Even though the free version is subpar I will not be paying for an app that is so glitchy just because you have to run ads. So many lessons have glitched before I’m even done drawing the step just to play an ad. Ridiculous, to be honest. And I do not agree that buying the app should be the solution here. Giving 2 stars because the lessons are fun, but the amount of ads are just not worth it.
