I have noticed my workouts do not get updated on Garmin after Athletica has updated them for load management reasons.
Examples:
Today I had a 45min run scheduled on Athletica, 50min on Garmin
Tomorrow is a 41min run instead of initially 1h run. Garmin still has 1h scheduled in the calendar.
Same happens for the swim and bike.
As a workaround for now, I can manually sync workouts from Athletica web calendar.
