My understanding was that I could invite a member into various levels of visibility of my board. For instance, my board is designed to manage a luxury home, so I have lists on that board for: housekeeping, landscaping, household inventories, contractor information, etc. I thought that I could invite the housekeeper, landscaper and handyman onto their respective lists, and that the other lists on the board would not be visible to them.
But when I invited the housekeeper onto the housekeeping list, I found out she was able to see all of the lists.
Am I doing this wrong? Or did I misunderstand the hierarchy of permissions?
