iOS Client ID resetted at app launch
We have a problem with the comparison of new users VS existing users, new users are way too high compared to different analytics sources and app downloads.
After further investigating it, it seems that every time the app restarts the `kGAIClientID` property of the current tracker is set to a different value.
I've tried setting the client id value to a unique identifier per device but it seems that this property is read-only.
It's been messing with our reports for a very long time now, is there any way to fix that?
We are using Google Analytics iOS SDK 3.17.
