 SMB authentication
 ^^^^^^^^^^^^^^^^^^
 
-In some cases (such as when using login credentials) it's not possible to read the
-smb credentials from the storage configuration, in those cases you can provide
-the username and password using the ``--username`` and ``--password`` arguments.
+Update notifications are not supported when using 'Login credentials, save in session' authentication.
+Using login credentials is only supported with 'Login credentials, save in database'.
+
+Even when using 'Login credentials, save in database' or 'User entered, stored in database' authentication the notify process
+can not use the credentials saved to attach to the smb shares because the notify process does not run in the context of a specific user
+in those cases you can provide the username and password using the ``--username`` and ``--password`` arguments.
+
+Decrease sync delay
+^^^^^^^^^^^^^^^^^^^
+
+Any updates detected by the notify command will only be synced to the client after the Nextcloud cron job has been executed
+(usually every 15 minutes). If this interval is to high for your use case, you can decrease it by running ``occ files:scan --unscanned --all``
+at the desired interval. Note that this might increase the server load and you'll need to ensure that there is no overlap between runs.
