Hey @Phoenix, after our most recent update on our pricing plans, all users who share the same email domain as the app creator or an app builder are considered team members/internal users by default in the system. If you look closely, everyone with @phx.se is a team member in your user table.
Please check this post for more details: Let your apps scale! A small update to our pricing plans.
I hope this helps to clarify. Sorry for any confusion.
