Why Can't Sub-Accounts See Any Books?

By design, newly created sub-accounts have no category permissions. Admins must grant category access explicitly.

Grant Access

1. Sign in as admin.
2. Open Category Management.
3. Enter target category.
4. Open permission section and add sub-account.
5. Save changes.

Apply Changes

Permissions apply immediately. Ask sub-user to refresh or re-login.

Tip

For broad access, create an "All" category containing all books, and grant that category to target users.
