Soft off only turn off the left side of my Corne split keyboard

[picrots]

I recently built a wireless Corne keyboard on the original v3 PCB design which doesn't have a power switch.

To turn my keyboard off I setup a keymap to trigger the Soft Off feature and it does work however only on the master side and the right side stays up.

I tried to create additional key map on the right side but that also only turn the left side off.

I am using Corne V3 and Nice!nano controller. My last build was through github action on 15th Apr 2024.

Same here, also there is a discord thread with some other people having same problem: https://discord.com/channels/719497620560543766/1225441220311126106/1225441220311126106

Duplicating my comment from discord: Looking at https://github.com/zmkfirmware/zmk/blob/main/app/src/behaviors/behavior_soft_off.c#L79 and https://github.com/zmkfirmware/zmk/blob/main/app/dts/behaviors/soft_off.dtsi#L12 Tried

&soft_off {
    split-peripheral-off-on-press;
    hold-time-ms = <5000>; // Only turn off it the key is held for 5 seconds or longer.
};

Even commenting out hold-time-ms (just in case), but without luck

edit: Uploaded a USB logging firmware plugged into the right side, the messages are

Looks like the behavior_dev is being truncated somehow.

This problem has not been resolved for me yet and right side of my Corne stays awake. Build date: 10 May 2024 (using github actions)

Can you check #2300? Also use my ZMK repo to verify if that's your case
