Unfortunately this is also an issue with the QR Code format which is underspecified, and this extends to a bug we've been begrudgingly waiting for apple to fix here.
The QR Code format is something like this
```
type = 'WPA'
return `WIFI:S:${_ssid};P:${password};T:${type};${hidden};`
```
So the long standing bug (feedback id 9991042) we have filed with Apple is about a downgrade issue with QR Codes. If an iOS devices connects with a QR Code it will successfully connect with WPA3. But when the device goes to reconnect it has saved the SSID as a WPA2 network only and will incorrectly only authenticate with WPA2. This is very unfortunate because the zero-knowledge aspect of dragonfly in wpa3 is a huge step forward for wifi security. Although I guess it's all still resting on AES CTR at the end of the day :-)
