My Forerunner 35 (v3.60) recorded two activities properly on one day... I can see the activities on the watch, phone (iPhone 13, 16.0.1), and I can see them online, but no intensity minutes were recorded (there's at least 50 minutes at HR level 2 and 3). All my other aerobic activities have intensity minutes recorded, but the intensity minutes didn't get recorded for these two on this one day. I've synced from both the watch and the phone, turned both off/on, signed out of the app, even uninstalled and re-installed the app. Still no luck. Online, the activities are listed (and appear to be accurate in terms of time, HR, intensity, and distance), the page says "You do not have timeline data for this day.") I know intensity minutes are a popular (unpopular?) topic here... any idea why this one day didn't log a timeline or the intensity minutes? (Activities since have been recorded, along with intensity minutes, just fine).
