Rode for about 50 min. Everything great. Got my first epic KOM. Super stoked. Ended the ride. Hit the upload to Strava button and poof, all gone. What gives? Found .fit file through my iTunes account and up loaded to Strava. But it’s as if it never happened on Zwift. I didn’t get any credit for my KOM hard work.
You can submit a ticket to Zwift support so they can review your log files. I am guessing you had an internet issue that caused this if it has never happened before.
