2.4ghz Band not enabling with PIFI USB

Hi, I have the pifi USB with a rpi 5 and every time I try to enable the 2.4ghz band it never enables. Is this a known bug?

No, it should enable.

Can I ask which model of Pi 5 (and also which firmware version - shown in app > settings > more settings > system report)

I’ll test under identical conditions to see if I can replicate, my Pi 5 freshly setup with latest firmware + USB is still working fine. But happy to investigate.
