Cannot add new TopoActive Map to Garmin Epix Gen 2

On my Epix Gen 2 watch I can go to Menu / Map / Map Manager / TopoActive Maps and then choose the "Add Map" option it connects to Wi-Fi (successfully) then shows the "Requesting Map Update Data" message but then the watch justs vibrates and goes back to previous screen showing only the maps I currently have downloaded (Aus & NZ and Africa).

I found this old thread that describes the same problem but it says resolved... ?

Thanks for any help you can provide!
