Has Huddersfield away sold out?

Does anyone know is it unreserved seating or do you have to sit in your seat?

 

Tickets had a row and seat number on, but a lot of away grounds tell you to sit where you want.

 

Which is wrong and one other reason I’ve stopped going away .
I’ve been left stranded with two small grandkids with someone on our seats and no seats together for us .
Luckily we have some fantastic fans among us and room was made so we could sit together .
But we shouldn’t have to rely on this , and even though those fans were kind enough to make room , others decided it was a good idea to stand up even though they were near front which made others in front of us have to stand ,
Grandkids didn’t enjoy the experience and missed a lot of the match and had to endure listening to swearing from people being asked to sit down. .
