- I had a multi sport activity in Garmin connect and it has disappeared. I can see it in the watch (Forerunner 735x) but it is not being synchronized with the app…Do you know how it could be solved?
As trux mentioned, try a manual upload. If you get any message other than Import Complete, then there is a problem with the file being corrupt. Attach it to this thread. We can look to see if it is repairable.
