As of late (maybe since the last update), the heart rate data seems totally messed up. My watch (garmin forerunner 255) suddenly reports that I'm at 145BPM while running at 12.2 km/h - which never happened.
The charts in Garmin Connect shows sudden increase in BPM, while my pace, elevation etc remain quite the same. Don't remember feeling bad either so... This is very strange.
Exemple
Is something wrong ?
