Approach G80 Green Contours

I have a brand new G80. It has been updated on Garmin Express, connected to the latest Garmin Golf app on my iphone 15 Pro and synced. I am subscribed. The app and the device have been deleted, cleared and reloaded but still no contours on the device.

Problem is that although green contours are present in the app, they are not present on the device, after over an hour of chats and telephone guidance, the best advice I received was to try it on the actual course and see whether it works then.

Any ideas?
