I just tried to set up Ubuntu 20.04.1 LTS Focal Fossa on a Raspberry Pi 3 B+ and ran into this bug. I used the ARM 64-bit image from this page: https://cdimage.ubuntu.com/releases/20.04/release/
I was able to use my 2.4Ghz SSID just fine. Tried switching back to the 5Ghz and failed. Went back to 2.4Ghz for now.
