Hi
I ser many old posts with same problem, but no solutions. Training is quite similar as for many years, but suddenly a week ago my Fenix 7 stopped giving high aerobic training load for intervals and tempo runs (which I always got before for exactly the same training). I suspect it is related to the most recent software update. I have not changed any settings or zones. The activities are mainly in zone 3 and 4 still, but only counted as «low aerobic».
