I applied for my sons first passport 19/4, I received a text to confirm documents received 03/05, then same text 06/5. Looking on forums, it may mean that it has been passed to a different office. My sons application updated 8/5 to say it was being processed and has stayed that way since. Apparently it is waiting for an examiner, 7 weeks this week since applied via post office digital check and send. I hope you get sorted in time for your trip.
