It doesn't see the same level of promotion that a Star Wars or MCU show would, but it's up in the big title card on Disney+, and there have been ads running that I've seen. I love the hell out of it, but the majority-think in this sub tends to be that Disney+'s only worth is in how many MCU and Star Wars franchise shows it can pump out for them. The Disney live-action shows like Mysterious Benedict Society, Big Shot, and The Mighty Ducks: Game Changers tend to get cold-shouldered.

I will also say, as great as the show is, the books are still better. The books can carry off things they can't do in live-action, like Constance being a toddler.

If you're looking for folks talking about the show, then r/nicholasbenedict might be a better bet than here.
