I‘ve tracked more than 500 rides with my Wahoo Elemnt Bolt and synced them on Strava. I noticed that some activities I tracked long time ago are not displayed anymore in the Strava activity section. I did not delete them. Whereas all rides are still counted in the personal statistics, the number of total kilometers is incorrect. ~4000 km are missing. My aim is to restore the complete track record.
I could add rides summing up 4000 km manually in order to correct total kilometers, however the problem is not the number of rides (which is correct) but the missing kilometers.
Does anyone have an idea what causes this issue and knows how it can be resolved?
