You said they made dining reservations for you but you can’t see them.
I couldn’t find mine either until someone pointed out how to do it.
once you are on the app, click on the “Book Dining” tab underneath the number of days until embarkation. Then in the upper right hand corner there should be a calendar icon with a red heart. Click on that. See if your reservations show.
I know lots of people report having problems with the app, but for us it has always worked fine. Guess we are lucky.
