It's impossible to share, whatever the way, the link of the Top 100 playlist generated in the Wrapped 2021. When people open the link sent by a friend, displayed in a Community post or on a website, they only get their own Top 100 playlist.
Edit : Workaround for avoiding this issue and share your Top 100 2021
Create your own playlist from your Top Songs 2021.
On desktop: CTRL/CMD + A in the playlist > right click > Add to playlist > Add to new playlist.
On mobile: Tap on the three dot menu in the Top Songs playlist > Add to other playlist > New Playlist
