I was doing some off-grid testing on my Powerwalls today, and I have noticed some of the time the mobile app displays a menu item and graphic for "Performance" (what I am accustomed to) and other times it has a graphic for "Impact". At first I thought it was because I just had a newer version of software loaded, but now I'm back to seeing "Performance". What's the difference and why would I see one over the other? Running 1.40.2 on the Powerwalls, iOS app 3.10.09. Rooftop solar from Solar City, installed about 8 years ago. Powerwalls were installed in March of this year. Thanks for any clues, Bruce.
