I think I see.
the wording is slightly different in the documentation from what is actually in the bundle configutation..
the actual wording is "All users -All the users, anonymous, or logged in, can preview attachments, and use 'Verify Step' in forms"
the text in step 12 says "All users - All the users, anonymous or logged in, can preview attachments, verify and sign forms".
This is the option to pick at step 12.
Is that what you mean?
