A user needs specific authorization to be able to make and adjust teams and their planning in the Location Manager.
Go to the Location Manager and log in with your credentials.
Select the 'Planning' tab and the appropriate combination of Week, Day, Brand, Channel, Office and Project.
Select the team to which you want to add crew members (selecting the desired team will make it turn a shade of green and make the 'add crew member' button visible)
Upon clicking the 'add crew member' button a pop-up will appear allowing you to select the desired crew member(s) from a list of Field App users.
Once you have added the required team members select 'Update crew'.
