Does anybody know how you earn energy points in the new app? I had the original app (now Walkathon & Fitness tracker, I believe) and yesterday I switched to the new app. I like the new layout, but it doesn't give me any of the challenges that the old app did, so I'm not sure how to earn energy for MyLand.

I am also totally in the dark about how to earn energy and what the details and finer points might be.  I am stuck right now with no land to free for more and not enough energy in more than a week to get another piece of land open.  Help!
