I've noticed when I go to my membership dashboard every once in a while it will have updated a bunch various users to another level.
"I will grant access for you to see what I mean."
I'm not sure why it is doing it, and it is enabling users to access content for members only.
While you're in there would please make sure I have it set right. I'm worried that a user has access or something and is upgrading people for some reason.
