ATEEZ not in 2024 MAMA line-up?

How does MAMA decide its artist line-up? ATTEZ rocked kpop global presence in 2024 with Billboard #2 ranking, first ever kpop boy band to perform at Coachella, first ever kpop artist to headline & perform at Mawazine Festival, etc.

Considering the above, does anyone know why MAMA, which will be a 3-day affair, is going without ATEEZ?
