my sister and i got V3 tamagotchis for christmas. i had one when they first came out so i could help her. when we try to connect, it says "STAND BY" then the screen goes back to our tamagotchis. they can't play, visit, or send presents back and forth. is our tamagotchi's glitched? or is it that they are not the same age. or is it niether of them?
