Hey fine people!
So I'm syncing only via garmin express on Windows and my fitness data (steps, etc.) is missing, except on days where I had an activity. E.g. I made 10k steps on Wednesday and 10k on Thursday and did a run, the Thursday step data is synced and the Wednesday one is missing in garmin connect. Funnily enough the data is still there on the watch,because it shows me the last couple of days.
I think this behaviour started with 3.80 but I'm not enterily sure, since honestly I didn't care too much about it.
The watch is a normal FR 45 with 3.90 currently installed.
Cheers
Johannes
