Have made a few edits to the map but when I have gone back to close them after the tiles have been updated, the changes whilst inside the editor are there I tend to also check the live map but the edit does not show up but checking via the app it does show.
User here had an issue routing to Sitel taking him to the wrong car park. Again updated but not showing in the live map but correct via the app when routing there.
Live map not updating is a problem that goes back for, literally, years.
Note that routing in the livemap is always as up-do-date as the Waze app. This is because the points you select on the livemap are then passed to the routing server that returns the results.
But the visual part of the livemap is often out-of-date. You will also sometimes find that it has updated at some zoom levels and not others.
