Cant learn, continue button is gray and unavailable

Question

Idk what happened to the app but I can't learn new lessons in every course, the very first step at every course is not letting me go further, the continue button is gray and is not clickable, what's wrong?
Btw I paid for pro version now and previous lessons that are open for pro version of the app are working fine, but not new lessons
