I had the same problem a few days ago. But i found a way to solve it (it worked for me, maybe not for you).
You have to download EA-desktop (https://www.ea.com/ea-app-beta) and when you have downloaded it you have to exit origin and then open the app (Look at the pictures). Then you need to add your friends and let them accept your friend requests. IMPORTANT NOTE : Your friends need to download the app as well and do the same steps as you but he needs to accept the friend request instead of sending a friend request. Then exit the EA-desktop, relaunch origin and your friends should be there. Underneath you will find the order to look the photos at. I need to reply twice because you can only add 3 photos in one reply and I have more than 3. My English is maybe not so good because I come from Belgium, sorry for that.
This is the right order to watch the pictures:
1) Arrow bottom right corner
2) After you click on arrow
3) EA-desktop opening
4) Adding friend (check next reply)
5) Exiting EA-desktop (check next reply)
6) Friends should be there (check next reply)
