ArriveCAN app problems - solution
I have complained a couple of days ago about not being able to enter my vaccination data into the ArriveCan app. I found out what was happening today. When entering my data, I claimed an exemption as an essential worker. When I did this, the app wasn't asking about a vaccination at all. This happened with both the phone app and the on-line portal. So do not claim any other exemption if you're vaccinated.
