As of right now it's been exactly one week since I was last able to share in facebook in order to get the rewards. Same issue appears in a close friend of mine with which we play together, although he had the issue 1 day late. We should be sharing same IP adress because we play from our work spot. Maybe the issue is on our side but I'd like to know what it is and if I can do anything to fix it. If any infomation is needed I'll gladly help!
