Conan must go season 3 announcement?

how is there still no trailer for the new season? the previous two ones were posted like a month in advance before the start of the season, meanwhile this time three weeks are left and still no trailer. Which isn't an enormous difference but i'm pretty sure usually trailer should go out way before a new series starts. the weirder thing is that they haven't even properly announced it or anything not even in their official social medias or podcast (as far as i know). I mean the knowledge we have of it is just through google and imdb (and the hbomax streaming website i suppose is where they got the air dates from)
