Just a heads up that on March 7, 2019 Google+ APIs and Google+ Sign-in will be shutdown completely. This will be a progressive shutdown; therefore, api requests to Google+ will start failing intermittently as early as January 28, 2019.
Furthermore, OAuth requests to Google+ will start failing intermittently as early as February 15, 2019.
How does this affect you? Any Klips and datasources you have created using Google+ will stop refreshing intermittently as Google+ APIs shut down progressively. As of the March 7th service shutdown, your Google+ Klips and datasources will stop refreshing altogether.
For more information please visit Google+ API documentation.
