I've seen many ambiguous errors in this process, but not "deserialising"!I have the app and, thanks to all the posts re using FirstnameMiddlename, had no issues with bringing up the QF reservation. I can see SEAT with a pencil, presumably for editing, for each passenger but when I click on that I get a "deserializing error". Am I doing this correctly or missing a vital step in the process? Tried emailing the local CI office and was told that QF bookings can't select seats.
