I flew with it (IOS 12 and FF) today. The only negative I found was that the "distance rings" around my ship seemed to be fixed size, and were not labeled. They used to be labeled with distances and would change sizes as I zoomed in or out. I changed the settings (to auto or fixed size) a few different times with no effect even when I closed foreflight (by double clicking (reducing the apps to "mini pages") and swiping them out of the way. I'll be interested if anyone else sees that.
