After recording an activity on my Garmin Edge 540.and syncing on Monday I wanted to check my training load and saw that it was lower than expected and around 3 weeks of activities have suddenly stopped appearing on my training load chart. They were all there before the weekend.
I can still see the activities individually in Garmin Connect, and they appear on the exercise load tab but my training load chart is missing the data. I generally have 3 sources of activity, Garmin Forerunner 245, Edge 540 and a sync from Zwift. Any ideas on how to force a sync would be appreciated! I've tried editing an activity to add some gear and perceived effort. I downloaded one activity as a fit file and re-uploaded it. I've also created a manual activity. I tried turning off physio sync on the phone and did a re-sync. I'm totally out of ideas!! Thank you!
