So, I used the app and scanned my passport and husbands. I added photos and credit card and it wouldn't go through all the way. So I signed into Celebrity on my laptop. This is where is gets weird, it had my birthday the same as my husband. Had me marked off as MALE, and my passport number correct, but expiration date was the date on my husband's passport. I scanned the passports, so this was not me manually doing it. Once I fixed everything on my computer, it then showed up in the APP and all checked in. And I was able to add to my iphone wallet from the App. So very odd. So if you're having problems with the app, check the website and make sure everything is correct.
