Announced Feb 20, 2023: Queen Mary's Global MBA curriculum has received full AACSB accreditation.

I believe you are mistaken. The business school at QMUL has AACSB accreditation, but the Global MBA is awarded by the University of London and not by QMUL. Only students with degrees managed by QMUL will get degrees from QMUL.  QMUL simply provides academic direction to the Global MBA. QMUL does not accredit it. 

PS We discussed this a few years ago at: https://find-mba.com/board/uk-ireland/university-of-london-global-mba-queen-mary-55015
