Can I change a member to an Admin?
If you’re an Admin, you’ll be able to change a user that has a member role to an Admin role.
Go to your Admin panel and select the Member tab.
Locate the user and hit the menu icon to left.
You’ll see the option to “Edit” and you can change the user's role from there.
Your Business account can have multiple Admins––there’s no restriction in the number you can have.
