Microsat shared some details about the DRO A/B mission.
"Through emergency orbit reconstruction, after 167 days of maneuvering, 5 orbit control adjustments, 5 trajectory corrections, and 3 gravity assists from the Sun and Moon, the DRO A/B composite successfully entered a DRO orbit, achieving successful separation of the dual satellites."
"Achieved the world's first large-scale autonomous constellation construction at a distance of millions of kilometers. Enabled low-energy orbital insertion with a velocity increment at hundreds m/s level, ensuring long-term stable DRO parking measured in years."
This seems to be the first official confirmation that the DRO A/B satellites have successfully entered DRO.
