Training Peak Sync issues to Enduro 3

I recently got an enduro 3 after years of using COROS watches for my running. 

I have linked TP with GC but the workouts in TP do not move to GC calendar. I have tried every trick on the internet, contacted both Garmin and TP and still not resolved it.

The workouts go to my COROS app and data from the garmin goes to TP but for some reason, the structured workouts won’t sync. 

anyone else been able to resolve this?
