Demon Slayer: Kimetsu no Yaiba Entertainment District Arc to simulcast on Funimation

Maybe, the issue is that the UK had a delayed theatrical compared to the US & Australia. It might show up next month or the month after but don't be surprised if they're saving it until the home video release is sorted.
Ah I see, that makes sense. Ho hum, there's certainly no shortage of anime to watch (& re-watch!) so I shall hopefully eventually watch the movie when it's released before season 2.
