Hello Librem 5 Community,
I just tested successfully connecting Librem 5 to a WPA3 network as a client.
I used the application Advanced Network Configuration and created the Network Connection profile there with manually entering the SSID, password, and setting Security as WPA3 Personal.
Afterwards I went to Settings -> WiFi -> selected the new network and connected to it.
It works! And the process is user friendly.
I am very happy, as Librem 5 was my most important device that was not using WPA3 yet.
So the only thing left regarding the topic WPA3 is to make the Librem 5 hotspot to use WPA3. I tried it through Advanced Network Configuration, but unfortunately, when I start the Hotspot, the config gets overwritten.
