For athletes near the bottom of the list of athletes, the "load" button is hidden off the bottom of the screen. You can still load them by dragging and dropping them onto the calendar.
In some cases, if an athlete or coach is interacting with a planned workout when the completed workout file syncs from the Garmin Connect Autosync the workout Quickview values won't be automatically filled in even though the file is correctly attached to the workout. In this case, the coach and athlete may still receive a notification, but the Quickview will appear empty, but the expanded workout view will look normal. To correct this while we work on a fix you can click "files > recalculate" in the workout Quickview.
Some .fit files from some models of Lezyne cycling computers don't display correctly in TrainingPeaks. This is an issue with the way the files are formatted so a fix will come from Lezyne.
