Where is FIT file

Yesterday I completed the Mega Pretzel and got the banner and the badge. Unfortunately it didn’t update Strava so I tried to get the FIT file but all I have is the map image with ride stars on the feed. It won’t load anything else. Any one know where else I can find my FIT file please?
