Hi, we are an organisation on the free tier. I had 5 members invited, including me as an admin. I have one Machine Identity. This worked great, but when the time came to remove a member and add a different one, I got this error message. Thinking that maybe because of the Machine Identity I have a total count of 5, I removed one more member but I am still getting the error message. Am i wrong in my counting? What can i do? Thanks!
