Hi
After the 18.20 beta release I had to disable the 3d distance and 3d pace features because, for every 0.1 mt. of movement, it calculates 1 km of movement. I have checked all the settings, units, etc. but until I disable the 3d distance feature, the inaccuracy in measuring the distance is crazy. This was never the case earlier and my watch on the same settings was working fine to calculate the distance but then after the 18.20 beta update, measuring distance is all wrong. I have made sure that GPS is put on all different modes but no success till I disable this feature.
The same is true with 3d pace. I completed my 5 KM run in 35 mins so, avg. pace should be 7 min/km however, during the run many times, the pace reading stayed at 2.35 min/km. And then suddenly it will jump to 6 or 6.50. For a run of 5 KM that I completed in around 35 mins, my average. the pace was 3 km/min - completely wrong. And once I disable this feature, the readings are now accurate.
