Equestrian sports workout app map not working

The equestrian sports workout app map shows my location on the map when I initiate it. But it shows no movement after that location. Everything else works, just not the map. This is not a GPS or location services issue, because if I use the outdoor hike workout (while trail riding on my horse), the map accurately records my trip.

I am using an iPhone 17 with liquid glass and an iWatch Ultra 3
