Hello! I'm just not sure why I have to wait for  the challenge to be unlocked when i am a subscriber? And commit to a certain day. My schedule changes so that's super inconvenient. 

Hi Danielle, challenges are meant to support your daily practice as you receive an email notification on the day a class unlocks and a reminder if you haven't watched a video in a few days. The classes stay unlocked once you've signed up for a challenge, so you can always go back and watch them again. It's just a different way to motivate practitioners and enthusiasts.
