I turned on google plus API in the developer console four hours ago.
Can someone help me, please? Maybe I forget to check API anywhere. Checked in the google-services.json Maybe it's because I'm testing it from emulator. Can't test in real device now
I've reported the problem on the Google Issue tracker and they have closed it as won't fix stating that it's deprecated
