If you skipped or denied one of them, open Settings → Privacy &amp; Security → Health → TrainInsight and toggle on Heart Rate Variability, Resting Heart Rate, Sleep, Workouts, VO₂ Max, Active Energy, Body Mass, and Time in Daylight (iOS 17+). The app reads everything; it doesn't write back, so the toggles you grant only affect what shows up in the dashboard.</p>
