Revealing the HUD after hiding it causes the route progress bar to disappear.
On what platform? Works fine on Windows here.
That’s odd, I’m on Windows too. I’ll try to reproduce it on my next ride.
I tested it after I saw your post. Maybe you took a manual turn without realising (the directional arrows are still live with the HUD turned off) which would take the route progress bar off.
Or, perhaps you finished a non-circuit route, like Valley to Mountaintop, while the HUD was off.
