Sorry, I might not be too clear. You don't need to click "message" but just copy the link you find below (on my picture marked as blue) and then come on here to this forum and post it into this topic just like you did writing this message/post, by pasting it into the message you're writing. So:
- click on the share symbol on the track you want to share
- copy the link you get in the pop up window which opens
- Come back here and start a new post in this thread
- you can of course write something first and then paste the link into new paragraph or you can paste the link first and then write something (if you want of course) in the ne w paragraph of the same post.
- click "Reply" button below your message and the track will show in your post.
Hope it's clear now. If you still struggle, let me know.
