Same problem for me using IOS 10.2.1 on iPhone 5 and miles/feet units. Also, the "current location" coordinates do not update while in compass mode.

Yes this is basically what I am getting. Only I can see the app is running in the background, (when you double press the start button),it just won't open, is stuck on the message page, and every time you swap to it or try to open I get the same as you - 20 odd seconds and then the frame closes. Is anyone looking into this? Would be helpful to have a response like the first poster did. Not sure where else to post this to get a faster response.... I also had the problem of the app not opening, and yet still running in the background on the message page with an iPhone 5. I deleted the app from the phone and reinstalled it and the app worked again. I've done this twice in the last few months. Looking forward to the bug fix next time around. +1 This worked for me. Thanks!
