The way she (and probably everyone around her) thought there were no singles to push and only bothered with "cardigan", when it turns out people were here for "the 1", "exile", and now "august" in equal measure. Welp. Although I'm also here for the fact that the album sold similarly to Lover with basically none of the same promo/traditional album campaign shenanigans.
i feel like it was more because she immediately dove into evermore after folklore’s release and knew another album was coming, so she just focused on that taking up her time. Had it just been folklore, I’d imagine she would’ve pushed more proper singles.
