This bug is caused by a change from iOS 8 of Core Location framework. Unfortunately, apple didn’t aware us clearly about this change in it release documents. In iOS 8, old code of location doesn’t work, it fails silently so we hard to recognise it fail. Core Location in iOS 8 requires some more attributes, and some attribute of checking for location status has changed.
