Fixed an issue that could cause private group activities to show sitewide after editing them.
In order to allow users to change the status of private group activities made public by this issue, we added the activity option Make private (the activity author / creator can access this option by clicking on the three dots icon, at the top right side of the activity)
The Make private option will display only on private group activities that are public, and will allow the activity author to return their status to private. Once you use this function, please ensure to refresh the page before trying to edit them again.
