Yes, this is the layout I get in landscape, but it's not picked up in portrait, so that it's just a bit too narrow would make sense for it not to be picked up as a large screen as the resolution is kind of weird when tilted into portrait instead of landscape.
Do you need anything more from my part? If so, or if you want me to test/change anything, let me know, I am happy to supply with whatever I can to help 🙂
Just happy to help 🙂
