Just quick scrolling on Twitter and Reddit over the last few days as well as some of TWICE/ONCE Korean Twitter accounts and fan pages.
But yeah situation ain't looking too good. Fanbase Twice_Trans has raised fund to pay for ads to run specifically in Korea and are asking for further donations for more promotion. Also a comparison of the broadcast promotion Alcohol Free and Scientist have compared to More & More. Sheesh!
Apparently K-ONCE is angry this comeback. Pretty much limited radio, no TV variety, no major advertising billboard/poster rollout or domestic i app advertisements, etc. Really poor from division 3 and Jyp Entertainment this time around. No digital single purchase on sale on Twicestore, albums sold out within days and has never been restocked on the site either. No US radio or playlist push either.
Difficult to think anything other than this comeback was just and attempt to line the companies pockets off ONCE's money by doing to bare minimum. Thank God the album is actually excellent to save this era.
