Exercise Rings not syncing

Has anyone found a solution for exercise rings not syncing with workouts? I went on an hour bike ride that did not sync- it shows it in the gps and as a workout with the correct time and route but my ring is still open- it shows 21 min of workout. I also took a short walk to try (9 min to close the ring) and it did not sync either! I had my phone both times. I’ve turned both on and off to try that but both devices aren’t showing the ring closed.
