This is frustrating. I cannot see this button either. I have been trying to get an answer to my question and no response. Can someone please assist me. I have a site manager on my two trees that in the last week cannot edit, add, delete anything. I have tried to demote and promote them to see if this reinstates their access rights and no success. Can someone please correct this asap.
Thank you for writing.
I must thank you - we have a bug in the help page that causes the button to disappear. Your post made us aware of it.
