Power meter keeps drifting upwards 40-60W. I have to calibrate every 10-15 minutes.
Gradient seems totally inverted now. Going up show negative incline, going down shows positive incline. The inclines are not correct though even if inverted, i.e. it shows -1% incline when ascending a 3% known climb.
Some profile screens just disappear. Yesterday on a ride, I used my music screen to change song. 20 minutes later, same ride, did not stop it, the music screen was gone from my profile and I had to re-add it while pedaling.
This is the flakiest Garmin update I've ever received for any edge or watch I own(ed).
