Problem syncing data from Garmin

[Gerald]

This discussion might help:

Gaps in the activities calendar

Is the data showing when you don’t filter on those dates? What type of activities do you have showing? It could be commutes, which is unticked (by default). When did you join, and are you waiting for it to populate? Have you been active in the last 28 days? To save Strava API call, you need to be active within a 28 day period.
