I bought an 850 last week for my bike at a holiday home. I use a 1040 on my usual bike and a forerunner 965 as my primary wearable. I used the 850 on two rides on subsequent days this week on mountainous roads. All the ride details uploaded to Garmin connect. But the secondary impacts , such as Vo2 max changes, FTP changes , recovery times , impact on battery battery, sleep coach didn’t. For instance after the two rides , my recovery time on the 850 was 47hours but Garmin connect and the 965 showed nil.Sadly, my Vo2 went down on the 850 but Garmin connect and my 965 still show the higher number. Any thoughts? . None of this is an issue with my 1040. Every bit of information has been consistent
