We are going to reuse our old Magic Bands for our upcoming March trip. When I went into MDE to link the Magic Bands, my old one shows up on the list, but my husband's does not. When I tried to link his by typing in the ID number on the back, I was told that it was already linked! Why isn't it showing up on the list of Magic Bands then? Should I call and double-check to make sure everything is linked properly?
