Does not work on iPhone. My son can not log in or out unless he is practically on my lap. He used to be able to log in or out from anywhere if we were at dr or shopping. FIX THE APP App is NOT fixed like stated. Can log in fine BUT location issues are not fixed. I am sitting in the home and it says I am blocks away. I even drove watching the distance go down, but as soon as I got to 20 yards, it started going back up. I wish the agency would use another app that really worked. This SUCKS!
