I have really mixed emotions about the app. This will be my fourth cruise using it. Once on board the ship, in my case, it has worked flawless. However putting my information into it prior to the cruise has been less than ideal. I realize it has been 18 years since I retired but I always considered myself somewhat computer literate. No longer. What I resent most is how companies just assume you know how to navigate their sites and input info they ask for. I feel like an uneducated person in so many cases now. It has, in honesty, taken away from me one of my greatest enjoyments of travel - the preplanning. I have accepted the 2 hour wait on the phone to talk to a live person over a simple question that could have been done in less than half that time before covid (how often do we have to hear that canned speech about covid causing so may extra phone calls). I accept the fact that the travel profession is having trouble getting their staff up to date (maybe they shouldn't have been so quick to downgrade) but I really would have liked them to give a youtube type presentation on exactly how to go about downloading passport and certifications on their site. To those of you who say they have no trouble with the app, I can only say I am truly jealous. I will just take my passport and cert that I have not been able to download into the app, smile and give the rest of the documents at the pier.
