Google Analytics will stop recording the Social Data Hub dimensions and metrics as of April 30th, 2016, and will remove the fields from the API after September 30th, 2016. You can update your Analytics Edge connector with these newly deprecated fields by clicking the Update button on the Fields tab of the Analytics Reporting wizard.
The fields can still be used in reports until they are removed completely after September, but you should take them out of any reports you are using them in. After May 1st, there may not be any data in the report anyways.
After you click the Update button, the fields will not be visible by default, but you can check the Deprecated box to see them.
All deprecated dimensions and metrics are visible in a (Deprecated) grouping.
