If you noticed that your manager is incorrect in Frankli by looking at the 'Org Chart' or from your 'Public Profile' view, it is likely that your Admin has made a mistake during your set-up.
It's an easy fix but to get this sorted, you will have to contact the Admin of Frankli in your company. This is likely to be the person who sent out the initial roll-out comms regarding Frankli or someone in your HR or People and Culture team.
