Had soms weird weight updates lately. I think I found out what’s happening. I sync from Garmin, had no weight updates there today. On my activity today, also synced from Garmin, somehow the weight on intervals is taken from Strava, not Garmin. Even though I have settings on syncing from Garmin it looks like weight was taken from Strava.
You don’t have “update weight from Strava” on so I don’t think it is that. Intervals.icu will use weight from the previous day (or earlier) if no weight is available and a new activity arrives. Maybe it is that?
Don’t think so as the weights are different. Last time I had this weight on Garmin was april 17th. But it matches the strava weight. Bit weird
