Agreed, didn't notice any blue or orange lines or indeed any signage of any sort when passing through on 30th March, just two long desks with queues being caused by people with the form on their phones unable to get the things to scan, much scratching of heads going on, there was a staff member on each desk inviting those with paper forms to come forward, no problem at all and away we went. I always take hard copies of all documentation, never have and never will put all my trust in mobile technology.
