Restaurant reservation feature doesn't work. Should be able to order room service from the app. Should be able to submit reviews and feedback through the app. Activities have vague descriptions. Shops should have a list of what they sell. Chat feature costs money when I think it should be free. Internet and Wifi was advertised before the cruise as free, but only the app is free to use with the guest WiFi. Had to pay $33 per device per day if you want internet access.
