Owners and admins have access to edit user permissions, but not email addresses. If you need to edit an email address, you will need to remove the old user entirely and add the new email address.
Navigate to Settings > Team > Members > Team Members, and locate the team member you need to change permissions for.
Editing A User's Permissions
Click the dropdown to select the new set of permissions, then click Save. The two options are Admin and Operations. If you need to change the role of the Owner, please contact Nash Support.
Once you click Confirm, the permission set will be changed. As a best practice, team members should log out of Nash and then back in to view the changes.
Removing A User From Nash
Once you select Remove, a window will open for you to confirm you want to remove the user from your account. If you're sure you want to remove the user altogether, select Yes, remove this member.
