I've downloaded all my activities from my old strava account and now tried to upload them again in my new profile. I'm doing triathlon, so there are a few multisport activities. While uploading the files strava ist mentioning "xxxxxxxx.fit duplicate of Morning swim". So far so good. But then checking the activities, all those files are uploaded twice. Is there a solution to get them only uploaded once?
Thanks for posting about this. Are you sure the activities are uploading twice? We don't support multi-sport activities on Strava, so it's possible you are getting multiple single sport activities (swim, ride, run) when you upload them.
If you're having troubles digging into this on your account, please submit a support ticket and someone from our Support Team will be in touch to help.
