Can’t look up journeys – Oxford Bus Company Review

I am trying to look up a trip from Oxford to Heathrow and I keep getting the message “No journeys found.” This is idiotic. Also, the 10 minute limitation on using the ticket is annoying. It induced anxiety for no good reason. You can simply purchase a ticket on board - not clear what the benefit of this app is.
