I didn’t once say on this thread which train I selected on the app. I did indeed select a later train so it would give me the discount, thinking that because it then gave me an “anytime day return” that it was a valid ticket for all trains on the day, and as I mentioned conductors never brought it up to me that it wasn’t.
It was only after some members here commented that there are rules regarding the use of a railcard before 10am that I realised it was indeed an invalid ticket for that early train, and that I was 100% in the wrong, albeit unknowingly.
Which is why in my eyes this is a good result, because I did hold an invalid ticket, and Northern could have absolutely taken me to court for boarding a train without an invalid ticket, but instead they offered me a settlement.
