Why can I no longer add friends besides my social media friends?

Hello @mrstpw Welcome to King Community. You should able to add friends in your game maybe the optio has updated and you will have to click on "Add" then you will see an option says "Invite" just click on that and send it to your all friends. Please check the attached screenshot for better understanding

For lives its true that you will always get request to send them lives compare to get livesbut you should keep sending them live request. Thanks
