So my girlfriends Apple Watch's rings randomly cleared themselves out today. Had them almost filled up, then all of a sudden they are not highlighted on the watch face complication. When I opened the activity app, it shows her two workouts she did and all her standing. Activity calories are at 0 but total calories are at like 1100. She stood for 14 hours and the bars are filled in but no rings. Restarted her watch and her phone. Any ideas?
