Gain is constantly improving, recently they introduced a new "members" admin feature where you can easily control if a member needs to be a team member or an approver.

It's ease to use and connect all your social media accounts. Now includes Tiktok.

I did an extensive search for a social media and marketing scheduling tool that would support client approvals. Gain is a fantastic solution! They are continually adding new features and release updates regularly. Highly recommend!
