I have the same problem, and don't seem to be able to switch it on my Android version. The graphic is a little different from the picture, I have seen it before but can't recall on which menu.
Could you help?
I understand, but I was trying to get it in get on the phone. I see that every once in a while it switches, apparently randomly. Two days ago I had flight rules, now I'm back to meters
Can anyone who uses the app on a phone reply, please?
