In my timeline, there was a message by Facebook saying they compiled a list of my most loved photos ("with overall more than 50 likes"), and offered me to share it. I chose instead to enter it to see what is in there. It looks like https://www.facebook.com/gwms/media/?set=a_verrrrrrrrrry_long_id&type=1&title=Your%20most%20Loved%20photos and there's no share button there. When I clicked back to return to my timeline the offer disappeared.
Is there a way to find this offer and share this compiled album? When I try to just share the aforementioned link there's no preview/snippet so obviously it wasn't meant to be shared like this.
