Hello! as we spoke on other tread, Windows Phone and Store are missing from the “Services” tab on Unity 5.2 (5.2.0f3), which causes the feeling that is no longer supported, please add them.
PC, Mac, Linux Standalone is supported, but in the new project wizard it asks for google id, is that correct for these platforms? Is there another setup wizard for these platforms as to me a google id seems only for android, I might be wrong?
Are you referring to the new project wizard on the Analytics dashboard? The Google API key should only be for Android projects so you should be able to just leave this blank with no issues.
