I have a Forerunner 235, and I use the Garmin Connect iOS app as well as the website. I have 13 workouts scheduled in the next two weeks on my Calendar in Garmin Connect. But when I try to send my calendar to the watch, only four of the workouts get sent.
In the Garmin Connect app, I press the icon that has the share arrow superimposed over the phone. I get a notification that 13 workouts will be sent. After pressing "Send Now", I go back to "My Day" and press the sync icon. The watch shows an "Updating..." screen and vibrates when it is finished. But when I go back to the calendar on the watch, only four showed up.
I wondered if some of the .FIT files were corrupt. So I tried mounting the Garmin to my Mac with the USB connector, and deleting all the .FIT files in /SCHEDULE, /WORKOUTS, AND /WORKOUTS/SCHEDULE. After that the watch showed an empty Training Calendar. But when I repeated the above steps, I got the same four workouts on the calendar.
Some of the scheduled workouts were "cardio" workouts, and I did have some days where more than one workout was scheduled. Wondering if either of those were the issue, I took those off the calendar. Nothing changed.
Any clues? Is there something else I can reset, without resetting the whole watch?
