How do I know when there is a new version of the Catalog to download?
Within the Menu section > Catalog list, a red "Update Available" message will appear under any catalogs that have a newer version to be downloaded.
There is also a pop up message informing you that you have a new version of the active catalog available to you. You can either dismiss the message or start the sync by tapping "Later" or "Install Now". That message will show only once per day until the Catalog is synced.
