Custom Challenges??

What is the “Turn-in” button for?

Good question. Lol I guess once I saw that you could forfeit ones that you didn’t like, I never bothered to think about it.

No idea.

Its so you can re-create the same type of challenge and do it again.

Once you have completed the challenge you may “turn in” so that you may free up a slot for your custom challenges, which will allow you to create another one in place of the one you just turned in. The credits will still only be given to you once the time that you set it for.
