You will now find Challenges on the iOS app. You can either tap on Challenges in the main menu ( the hamburger icon in the top left corner), or you can swipe to the right on the language flag to see the language panel, stats, challenges and achievements.
Challenges are a great way to stay motivated and push yourself to make a breakthrough. Let us know how you like the new update!
In my “past challenges,” it lists ALL the previous challenges, including ones I have not participated it and all the challenges for languages I am not even studying. Any way to make it show just the ones I attempted or at least for the languages I am studying?
