Adding waypoints since watchOS 10 Apple Ultra 1

Since the upgrade and 10.0.1 the waypoint function does not appear to work.

The blue parked waypoint is not showing on the compass app and there is no location map showing for the actual waypoint. (Even though the watch knows there is a parked car location)

There is no way to add a new waypoint either. I can get as far as clicking the arrow at the bottom left of the compass app which takes you to the waypoint screen. However, clicking the green tick to confirm the waypoint doesn’t do anything.

I’ve also noticed the latitude and longitude are both dashed out all of the time.

Yet the bezel display of coordinates is perfectly ok.
