I have to move all my diagrams off the system due to current system seems:
  1. By default mark all files Team file
  2. Team file by default is accessible via URL
  3. It is the same URL used by owner and the team members
  4. It seems even not Signed In User can access that file with the URL
This basically prevent me from using system to do any demo because the URLs can be captured easily if it is recorded. This is really big security bug and key to commercial usage.
