There is a difference between Removing a Member from a Level or Cancelling a Member from a Level.
Removed from Level: This removes the Member from the Level. So, there would be no record they were ever in that Level once they are removed. They are completely removed from that Level.
A Member would need to re-register or be added back to the Level in order to regain access.
Cancelled from Level: This cancels the member’s access to the Level. But, they remain in the Level. They are cancelled from the Level and cannot access any of the protected content in that Level.
A Member would need to be Uncancelled to the Level in order to regain access.
