Google have announced that the Google+ API is being deprecated on 7th March 2019. This has an impact on our ability to supply the Google+ Managed Source. Therefore, on the morning of the 7th March we will be deprecating the Google+ Managed Source and stopping all sources.
Unfortunately, we cannot carry on making the Google+ Managed Source available due to the API being deprecated. There are currently no alternatives for Google+ since the entire of Google’s social network will be removed in the coming months.
For more information, please see the Google+ API announcement.
