Flint 3 and Slate 7 Mesh network preventing WPA3 connections after previous WPA2/WPA3

Router
1

Config: Flint 3 (GL-BE9300) main router, another Flint 3 (GL-BE9300) mesh node, and a Slate 7 (GL-BE3600) mesh node

Firmware: 4.10.1

All radios enabled: MLO, 6G, 5G, 2.4G; guest and IOT networks also

Devices running MacOS and iOS 27.2.1 frequently are unable to reconnect to the network, showing "" was previously joined as "WPA2/WPA3", not "WPA3". This often happens when the device is moved from one location to another location in the home. After a long period of waiting, a connection sometimes becomes possible.

See attached screenshot.

Hypothesis/Guess: Could this be due to network security setups not adjusting properly when switching radios? For example, the 6G network only permits WPA3.

If not yet done: Don't use MLO + the bands on it's own with the same name.
The MLO name should be different from all others. Or you simply disable the other ones, since MLO uses the frequencies already.

Trying that, thank you!
