View a course on the Garmin Connect website, then there should a "Share" button in the top right. Just above the map, above the box which gives you distance/speed etc. Note the share button will be greyed out if the activity is set as private. You can change the privacy by clicking on the little padlock icon.
It's on mine. I'm using firefox. Try clearing your cache. It's only a 50/50 shot, but as ridiculous as it seems, clearing the cache sometimes will fix a webpage that's not showing all the buttons and other controls.
You need to make the course public and then you can share it VIA a link. This link you can share via WhatsApp for example however I did not managed to share the corrs via de application on the phone. Only via the web application.
I have found the solution so you need to make your course public you can do this in the application by editing the course. If you slide up from below you see a graph of the altitude below you see privacy. Below course name and type. When you set this to public you get the option In the upper right Corner to share the course. Not the most easy and direct way.
Would be better is you always had the share button in place and then you were asked if it's ok to make it public.
