I had this same problem, on the Medallion app, said blue lane, but on computer said green lane. Also on phone app no Dine Your Way or Wellness check. My solution was to uninstall Medallion app and reinstall it. I realized then my Medallion app was from a pre-covid cruise. By reinstalling with new app, everything works good now. Princess should have something in BOLD on website to do this. I also called Princess CS and they didn't help me. This is probably a known problem; it needs to be more widely broadcast.
