5.12.0.24 scheduled workouts are not sent anymore to my enduro 3

Hello,

With version 5.12.0.24 the scheduled workouts are not sent anymore to my enduro 3 even after many synchronisation in between the iPhone and the watch. All the data are well synchronised except the scheduled workout. I have checked in the Garmin calendar and the workouts are well there, but nothing in the enduro 3.

First time it happens. Very annoying.  

Thank you in advance for your support

enduro 3 firmware is 13.37.
