Garmin, please get rid off the night calibration or add a possibility to turn it off. It only messed my altitude from right value to wrong 50m off altitude. I also got new watch because of another problem, but this bug is still present. Even if I ended my activity in front of my house with right altitude, this value get messed at night with auto night calibration. I was asking this long time before...
There is still another bug which I post many FW versions ago. If I go to sun rise/set widget from a watch face, scroll to map and return to watch face, the altitude on watchface is changed to altitude of place, which was on the map, no matter if I moved to completely another place with another altitude (without starting activity). This happens ONLY ONCE per day and if I open the altitude widget, the altitude jumps to right value.
