Pinephone cannot connect to WiFi networks where “fast roaming” (IEEE 802.11r) is active

Right. It’s taken several hours of bashing my head against a brick wall, but I’ve finally been able to connect my Pinephone to my home WiFi. Turns out that having “fast roaming” (IEEE 802.11r) active on my mesh network was causing the issue. Does anyone know what’s causing this problem? I’ve previously had no issues on my Pinebook Pro with this feature active.

I’m not sure where the issue lies, but it was present on the latest Phosh & Plasma-Mobile builds.
