I just replied to another post about this, but then I went to FB and tried again. In my frustration I tried a couple of things. I put my cursor at the number of my birthday and pressed enter a couple of times. Then the "continue" button changed to green and I was able to play.
playing (or trying to) on FB and having same issue. I put in my DOB and the "continue" option remains greyed out. So cannot play and cant seem to find a solution anywehere. Do techs or staff read these posts ?
