Hello,
I know both are in “beta” but where does the bug lie to report? My SSID is using WPA2/WPA3 transition mode.
Why do you think there is a bug? I am no expert, but I understand WPA2 TKIP to be compromised. I thought KRACK was the end of WPA2 being considered very secure. It seems the warning would be valid especially when WPA3 is an option.
You should be using AES instead of TKIP. That's why.

How do I set that?
AES is used by default:
https://documentation.meraki.com/MR/Encryption_and_Authentication/Setting_a_WPA_Encryption_Mode
If not, you should get in touch with Meraki support as mentioned on that page.
This is surely an iOS bug. I don't think WPA TKIP / WPA2 / WPA3 is even a legal transition mode. I don't see any sign that 27.3 is broadcasting a network like that -- might be worth packet capturing a few beacons.
Looks like this has been fixed by 27.4. No updates on the iPad or Meraki dashboard except upgrading the firmware and the message/warning has been removed.
