All their stages are either pre recorded or just lipsync and their "Encore" had heavy backtrack and most of it was lipsync the entire time only Ning wanted to sing live (heard above microphone)
Fans are so used to auto tune and pre recorded vocals that they can't tell the difference between them and have set such high standards and maybe the members don't reach it (while doing choreos).
Also no one sings live at music banks anymore but the way sm made the girls to lipsync in encore like??
Anyways 2022 hope aespa is allowed to sing live since sm makes decisions like those specially with rookies.
