My husband has had Zwift and it is linked to his Strava Account. Last night I just purchased my own Zwift subscription and tried linking it to my Strava. When doing so it doesnt actually tell you what Strava it connects to which was weird. The only thing it showed was “Authorize” which I did. For some reason I finished my ride today and it uploaded onto my husbands strava. Then he did a 20km ride that didn’t upload at all… Any help greatly appreciated.
Do you both use the same device to Zwift? You might need to log into a different profile on the device and make sure that when linking to Strava that you have signed into the correct Strava account first.
