The menu that can be seen in the public facing Wi5 app is a static representation of the menu at the moment of publishing.
This can be updated at any point by Wi5.
It is possible for us to auto publish the menus right after menu syncing every night at 3AM (How to sync Wi5 menu with POS). This is something that can be enabled upon request. If there are any new items, they will need to be enriched before they appear in the public facing Wi5 app.
Please note that all new data including enrichments will be published.
