I have had my Vivoactive 3 since it was introduced. It has worked perfectly until the last two updates. Needless to say I am extremely disappointed. While cycling or walking, the elevation gain is highly inaccurate giving at least 3 or 4 times the elevation gain. The stairs climbed sometimes goes as high as over 300 in a short walk with minimal elevation gain. While pool swimming with strokes other than free style, the length swam is doubled. Note that while choosing BIKE will riding in a car (with sunroof open) the elevation gain is correct. I have reset the watch and started over without any improvement.
PLEASE correct this!!!! SOON!!!!! If not corrected, I will be forced to switch my wearable brand. I am a loyal Garmin fan and own 5 Garmin Edge cycling computers and 3 Vivoactive watches.
