Wondering if anyone else has had this issue. Trying to add a friend via their pin# but every time I try and send them an invite via PIN, I have no option to send. The "send" button is grayed out. I've tried everything and it's driving me nuts. I know I can scan barcode, etc but should be able to add someone by just their PIN no? I've verified not an isolated issue by trying to add other contacts by PIN#. Using Galaxy S3
