I having the above issue.
The Garmin Connect App is not updating these measurements from the FR970.
FR970 is showing the current measurements and is correct from the activities I have been doing but the App is not updating it.
I have tried closing and opening the app and re-syncing with the watch but no success to keep it both sync correctly.
Thus, the app is showing me Training Status as ‘detraining’ (VO2 max numbers are sync but load is 0 across) and my watch Training Status is ‘no status’ (V02 Max - no trend, HRV- no trend, Acute Load - high). I just got the watch 2 days ago. I understand V02 Max and HRV needs more data before it is calculated but not the Acute Load which should be synced)
Hope this makes sense.
