Garmin Edge 540 not syncing correct Garmin Coach workouts

Hi everyone,

I’m having an issue with my Garmin Edge 540 not syncing the correct workouts from Garmin Coach.

What’s happening:

  • The Garmin Coach workouts sync perfectly to:

    • Garmin Forerunner 965

    • Garmin Connect (Windows)

    • Garmin Connect mobile app (Android/iOS)

  • All devices show as successfully synced with no errors.

  • However, the Edge 540 does NOT display the correct Garmin Coach workouts.
    Instead, it shows older workouts or completely unrelated ones.

Troubleshooting already done:

  • Bluetooth sync

  • Wi-Fi sync

  • Sync via Garmin Express (Windows)

  • Manually deleting workouts and resyncing

  • Forcing update of calendar, activities, and courses

  • Full device reset (restored to factory settings) — still no change

Additional details:

  • The Edge 540 does show Daily Suggested Workouts, but not the specific workouts from Garmin Coach.

  • The Forerunner 965 syncs the exact same plan with no issues.

  • No external FIT files or third-party training plans are involved.

Question:

Is there any known limitation or compatibility issue between Garmin Coach and the Edge 540?
Is there another method to force-sync only the Garmin Coach calendar to the device?
Could this be related to a caching problem in Garmin Connect?

Any help, insights, or similar experiences would be greatly appreciated.

Thanks in advance.
