I read that in order to download your courses you have to:
Make a course in the Connect app
Go to the More tab with the 3 dots.
Click on Training and Planning.
Select Courses and choose a course to download to your watch… All according to their documentation: https://support.garmin.com/ en-GB/?faq=VUgW3ChoRg2j4TeIX59et8
However courses are not in my Training and Planning menu!? How do I upload the course I made??
Ps. I have a Garmin Forerunner 165 Music
