According to Google support ( I showed them a thorough video about how Google Login on my website using Krotek Social Login package has failed ) and they replied me with this message:
Dear Developer,
Thank you for your response!
We have noticed that your app is accessing the following scope :
https://www.googleapis.com/auth/profile.emails.read (Please refer to the attached screenshot).
The Google+ APIs were shut down on March 7, 2019. This includes Google+ Sign-in, OAuth token requests with Google+ scopes, and Google+ integrations for web and mobile apps.
Is is true?
