Conditional / expression breakpoints not working on NRF52840DK or working poorly

[SRA]

Using SES, nrf52840DK, the onboard debugger.

I am able to set a breakpoint and use condition like x == 5.

I am unable to use anything but the == operator. In SES I get the red breakpoint with a white question mark over it.

Tried read/write/default, hardware vs software break, all manner of syntax, local and global variables. Nothing seems to work except ==.

Thoughts?

EDIT: I followed the advice for SES here studio.segger.com/index.htm and here studio.segger.com/index.htm
