How do I get into Freeform mode? I got into it once accidentally, but in a recent Kendall bootcamp, she had 3 or 4 freeform sessions and didn't explain it at all, other then I think she said to set incline and speed to 0, which I did. But no sign of it. So I ended up sinking off the leaderboard, not metrics during the runs, even though I was pushing it as I would be in Freeform. I looked in the User Manual and they have nothing on Freeform, which is unbelievable if its really a feature of the tread. Come on Peloton, you have to explain this stuff. What am I missing?
