I have set up trello very new to it, i invited my client to her two boards, I work as a VA. and she was able to access everything, including my private boards and my other clients. I have gone to the access and my email is the only one and it says that they are team for the boards I invited her on.
This is quite a bad breach for me and if I can do this mistakenly then it is quite a bad situation for other VA.
Please help if you know of a way for me to rectify without deleting all of my boards
