On the progression tab I have synced activities from Strava and if I request year to date I only see a 4-month period on the chart plus the number of activities is only about a third of the actual number. Am I missing something?
Check the Activity table, set to Show 100, and verify page 2 and older looks fine with expected power data.
If the data looks fine file a request with support@xertonline.com and they’ll take a look at your account.
