I bought two tamagotchi V3's and I can't get them to connect to be playmates. Am I doing something wrong? I have followed what the instructions say, but it goes to "stand by" and then back to my lonely tamagotchi pet... I was expecting something different when I tried to make it visit the other or play a game. Let me know if you come up with anything... or if maybe I got defects and should take them back to the store to exchange them. Thanks in advance.
