I’ve tried restarting the watch and app, deleting the app, turning off blue tooth, pairing the watch again, nothing works.
You mean structured workouts as in the following, right?
(Connect app): ... > Training & Planning > Workouts
or
(Connect website): [left sidebar] > Training & Planning > Workouts
Stupid question, but are you pressing the button to send a workout to the device in Connect? Workouts don't sync automatically.
(Connect app): ... > Training & Planning > Workouts > [select workout] > [tap icon with arrow going into watch]
(Connect website): [left sidebar] > Training & Planning > Workouts > [select workout] > Send to Device
