Having an issue with Training Calendar sync on my 735xt with scheduled workouts syncing as regular ones.
E.g. when selecting a training plan the workouts populate the Calendar in Garmin Connect correctly and are seen as scheduled there, upon selecting "Send workouts to the device" the respective menu appear saying "XX workouts will be sent to your device" and the process seems to go OK, but upon sync end and "Updating" state successfully completed on the watch itself the Training Calendar still shows "Download your training calendar fron Garmin Connect" prompt. The synced workouts are however visible in "Workouts" section of the "Training" menu.
The issue persists when trying to sync the complete training plan and also a single scheduled workout (created and scheduled manually). I also tried syncing the watch via Bluetooth through Garmin Connect Mobile app for iOS and via USB from a Win-based laptop - the issue remains.
I browsed through the forum to found similar issues for other forerunner watches (220, 620), e.g. here https://forums.garmin.com/showthread.php?103933-Manual-fix-to-Training-Plan-events-not-uploading-to-220
On my watch however the "Garmin > Workouts > Schedule" folder is empty after the sync. Instead, I have a "Garmin > Schedule" folder which does contain a schedule.fit file. Deleting this file changes nothing. If I move this file to "Garmin > Workouts > Schedule" folder it gets deleted once the watch is disconnected and circles through "Updating" state.
Any help would be appreciated.
