I thought that custom list feed gone long time ago:
But actually you can still access custom list news feed with this URL format (x.facebook OR m.facebook both can work):
https://x.facebook.com/home.php?sk=fl_<LIST_ID>
List id can get from https://www.facebook.com/friends/friendlist , right-click the list item can copy list id of link https://www.facebook.com/lists/<LIST_ID>
I discover this because long time ago I created a custom app to launch custom friend list feed by clicking app icon, I wonder why it still working
(I chose this URL format because normal link not worked AND web browser required):
am start -a android.intent.action.VIEW -d 'https://x.facebook.com/home.php?sk=fl_<LIST ID>'
Or alternatively simply visit https://m.facebook.com/ , hamburger menu on right can see old menu custom list too. Thanks to this video.
