Tried to look at excursions for our various ports. On the ports we have not booked excursions, none show. (They used to show, which is how we found the excursions we did book.) I called NCL and was switched to the technical department. I explained this happened not only on my computer using Edge, but I also tried on a computer in the public library that uses Firefox. Their answer was their website only works well on Chrome, not Edge or Firefox.
BTW, also is no longer showing the place to book shows or dining when clicking on the day in port.
