Yeah and they’re now rolling that out to everyone, not just EU citizens. This sucks the most for visa nationals because their passport isn’t good enough to get into the country. They need the server to be alive and their documents linked to even make it to the border, let alone to cross it.
Travel to the UK is going to be really chaotic from 1st Jan when all BRPs expire, and 8th Jan when US citizens and other non-EU nationals require ETAs.
