Hi,
In general, MapRun does not publish results to the server for CheckSites events.
Results:
https://results.maprun.net/ only shows events published to the server by a MapRun Administrator.
This applies to runs in CheckSites events using your phone, Garmin watch or Apple watch and "GPS Track Upload" only lists published events.
I'm not sure about Get Track from Strava... It may show the result on your phone - but it wouldn't upload to the server.
Could you please clarify what you are seeing. Send details to support@maprun.net if you don't want to share your CheckSites event here.
Peter
