@Jan-Suchánek said in Software Update 2.44.46 (2025 Q3): @isazi Also the option for wheel circumference Is missing for speed sensors. How does it work now? Only automatic calculating after some distance? I hope you’re wrong because I use the Bike Sensor indoor so no GPS signal to determine the distance.

@pomah86 If you look at my posts a little earlier in this thread you’ll see that tech support acknowledged that there was a known issue in the fw 243.2 release affecting stability. When they tell you “…rest assured this case is a top priority for us and most of our engineers are working hard to fix it”, then a couple of months go by, a new fw (beta) release comes out and you see the issue has carried over to the new release, it’s not difficult to become a bit cynical when it comes to one’s level of confidence that known bugs will actually be fixed. That said, I’ve rolled back my fw and will wait until a final, supposedly stable, release comes out and continue to be hopeful that this issue will finally be resolved.

@Steven-Hambleton During serious activities I use the H10 strap. During rest/sleep the oHR readings are OK. Besides, I knew very well what I was buying before paying even though I’d love a better oHR. Anyway, that particular watch, IMHO, is one of the best sports/mountain watches money can buy.
