This may be unrelated re: simplifications, but I noticed that if I have a workout that has some interval steps with targets, and others without, it is not functional on my Garmin.
This workout below is sent to my Garmin calendar and appears as a workout on the calendar, but when I try and send the workout to my device, it doesn’t sync. When I select the workout from my training plan on my Garmin (530), then it doesn’t show up as a ride I can actually do.
