User A (Notebook shared) -----> \ Common Info \ Sub-Notebook
1/ Anyone can see the pages under "Common Info"
2/ NO users with viewer permission could see the pages under "Sub-Notebook"


It's so strange of the Notebook sharing~ User A has shared his notebook "Common Info" and sub-notebook "Sub-Notebook" to group FIN with manager permission, and shared to group MKT with viewer permission (for both level). One day, the user in group FIN created a "page" under the shared notebook "Sub-Notebook", found that ONLY he can see the added page, others even the User A cannot see it~~~~ What's wrong in this case??
Also, the problem still exist - Users with Viewer Permission CANNOT see any pages under "Sub-Notebook", but can see the pages under "Common Info"....
Anyone from Zimbra could kindly help?? Many many thanks~~
