My watch has stopped making workout route maps after update to OS6.1.1

[Steveatesh]

I’ve just noticed that my watch has stopped producing the maps of workout routes and it looks like that happened when I updated it to WatchOS 6.1.1 and pay phone to iOS 13.3

I’ve tried searching through the system prefs and searching online for the answer but I can’t for the life of me see what setting I need to turn on to allow my watch to produce maps again.

im presuming that the ability to produce workout route maps was not done away with in the updates?

anybody point me in the right direction please?
