I checked in normally, then checked out after normally after the trip. But the app is showing "missing check-out" for the check-in at Amsterdam Centraal and "missing check-in" for the check-out 40 minutes later at Zandvoort-Aan-Zee.
Is this normal? I'm charged for 20 eur for missing check-out and my Flex tarief is not applied for my missing ride! This is awful!
