I think you are totally correct.
I believe this is will eventually take the place of paper, however it does still say you need to show the original vax card from US.
So, if it doesn’t work, don’t fret, your going to show your card anyway. We are testing for IT how this works! 😂
I was told by IT last week that they are making updates and it should show
approved prior to boarding, which in my mind, is when they have checked your documents to board.
If anyone has received an approval on the vax download prior to port day, I’d love to know about it.
