Unable to send Garmin Default Workout plan

This morning I am trying to send Garmin Default Workout plan from my Garmin Connect app to my Finex 8 Solar watch. Strange enough, the app says "Device not compatible". I can see older workouts to my Finex 8 , I have tried with all other Default workout plans but its still the same issue.. I've tried the following things:

- Update the app and my Garmin Finex 8 to the latest version

- Delete my device in the app and connect again

- Delete the workouts (Not such a good idea, because I don't have a single workout on my watch anymore.) I can no longer add the workouts I had on it.

Hopefully someone can help me with this problem
