Hello @Steve_Mansfield , I’ll flag this up at HQ to be looked into. It doesn’t seem like everyone is affected at the moment. To confirm, when you reconnected Zwift and Strava, did you grant Zwift all permissions (particularly the permission to edit data on your Strava profile)?
when I re-connected I didn’t intially select that option, because it wasn’t obvious I needed that ticked to get the upload. To test I’ve done a disconnect, a re-connect and when doing so selected all options
