The "Friends" stuff has never worked in the PC/Windows version; the buttons were there on a couple of the islands, but they just took you to a "Friends" menu in which none of the buttons or features worked. The menu showed a "Friend code" (which is the same as one's game ID code) but there wasn't any way for someone using the PC version to enter someone else's friend code. If someone on the mobile-app version of the game entered a PC user's friend code, they got a stranger... because the versions are run off different servers and there isn't anything to stop the two servers from generating identical codes.
