Im having the same issue. I can send offers as well but the recipient never gets them.
It shows up to others that I have no offers as well. When I directly sent the link to a friend and she tried replying and making an offer, she got a message saying "this user may have violate our policies and has been removed from offer up." WHAT?!
Ive NEVER violated any type of rule EVER with them. Ive gotten no reply from them either.
