I did this in March and it took me a while because my documents weren’t approved when I scanned them so I had to line up for a manual review by an agent. The line itself wasn’t long—I was the fourth person in line—but it took a while because the people ahead of me had a lot of items or were unprepared. Overall maybe 30 minutes but adding the time for the long security lines made me lose a bit of time despite getting to CDG 2 hours before my flight.
