You may need to remove a share — content that has been assigned or made available to a specific user or audience — if it’s no longer relevant, was shared by mistake, or is being replaced with updated material.
Removing a Share From an Audience
In the Thrive menu, go to Manage > Structures & Audiences.
Click the audience you want to remove the shared content from.
Click Content.
Locate the content you want to remove and click the remove icon.
The content is now removed from the user or user group.
