Confusion with chip revision

Hello,

I am using the nRF52832 WLCSP with the imprint "N52832 CIAAE0 2207A5", and my FICR reports a codepage size ox 0x400 and a code size of 0x100. This results in a size of 256 KB, right?

After looking at the compatibility matrix here I am left wondering how a flash size of 256 is even possible. Shouldn't all WLCSP chips have 512KB?

Also, shouldn't all CIAA revisions have 512 KB?

How is it possible that the attached application ever worked and why did it stop workingbootloader_with_softdevice_delay_nrf52.hex?

Kind regards,

Daniel
