Although I'm not appearing as an individual, I did travel with the app quite a bit. I have colleagues who are based in different regions around the world. We were certainly comparing notes about all the hoops we all had to jump through in order to facilitate international travel. There was some envy about the practicality of our ArriveCAN app in Canada.
As a user, I appreciated the practicality of it. I found it efficient. From that perspective, I think it was a good experience. From the perspective of what we were asked to deliver, I think the app was delivered securely and was reliable, in the sense that there was no inability for users to access it when they needed it.
