There is no draft feature. Lost hours of work making a challenge. I had done so much research, put in so much thought, then checked a text to help someone with research, and it just lost my whole thing! I had to call a helpline it was so distressing. it's ok if you aren't going to put in any time or effort, but i wouldn't bother making anything in the app. I'm heartbroken

Very limited categories for areas of improvement. Pretty pedestrian. And if you create a category, you have to make up your own progress steps. And I tried to unsubscribe, and it is impossible.
