Forget it. No one cares. Officially, Arrival Groups and Times are going away at the end of the month. Just show up at terminal for check-in when convenient for you as long as arrive by latest time indicated in Travel Summary information.
Together with the elimination of Arrival Groups "feature", the final boarding pass screen is completely a new design and besides QR code will have guest full name, ship name, departure date, etc, so much more like an actual BP. They are scheduled to appear about 11 days prior to sail date.
Correct. They may already have the new timing in place (not sure), but guests should expect to see the new BP around 11 days prior and this begins Aug 1 launch in the App (probably need to update it as well).
