My custom workouts won’t appear on Vivoactive 4

Hi, I’ve had a Vivoactive 3 Music and now have upgraded to a Vivoactive 4. I have created custom workouts on the IOS Garmin connect app and they do not appear on my watch. They will appear in the calender if I schedule it to a day but they will not appear on the watch anywhere else, which is very annoying. I like to have multiple workouts stored on my watch and don’t rely on my calender. Any help please, thanks?
