Re-authorization required to connect Facebook groups - August 1, 2018
In an ongoing effort to protect user privacy and data, Facebook has implemented an approval process for apps connecting to Facebook groups.
As a result, all Facebook groups connected to the Hootsuite dashboard will need to be reauthenticated with an additional step by August 1, 2018. After this date, group functionality will stop working and scheduled messages will fail to publish until the following steps are completed by a Facebook group admin.
Manage Facebook groups in Hootsuite
A Facebook group admin needs to add Hootsuite to the group as an authorized app within the group’s settings in Facebook. Then, the group must be reconnected to the Hootsuite dashboard.
See the Before you begin section in the Add a Facebook account article for details.
