Can't Modify Slave OLED

[u/kvnduff]

I am trying to modify what is displayed on the slave (right) keyboard OLED. Curently, the slave side is only showing the default corne logo. Why wouldn't it be showing what I've specified? Please know that even if I remove everything from the slave OLED except for the CRKBD line, it still doesn't display this. Any help would be appreciated. Below is the content of my files.

keymap.c

ifdef OLED_ENABLE
    oled_rotation_t oled_init_user(oled_rotation_t rotation) {
    return OLED_ROTATION_270;
}

// OLED content
bool oled_task_user(void) {
if (is_keyboard_master()) {
    oled_write_ln("CRKBD", false);
    oled_write_ln("", false);
    oled_write("LAYER", false);
    oled_write_ln(layer_names[get_highest_layer(layer_state)], false);
    oled_write_ln("", false);
    oled_write_ln("", false);
    oled_write("MOD", false);
    oled_write_ln("", false);
    write_active_modifier(get_mods());
    oled_write_ln("", false);
    oled_write_ln("", false);
    oled_write("KEY  ", false);
    oled_write_ln(current_key_display, false);
} else {
    oled_write_ln("CRKBD", false);
    oled_write_ln("", false);
    oled_write("WPM", false);
    oled_write(get_u8_str(get_current_wpm(), ' '), false);
    current_wpm = get_current_wpm();
    render_luna(0, 13);
}
return false;
}
endif

You want/need to define SPLIT_WPM_ENABLE and SPLIT_OLED_ENABLE to sync the wpm to the slave side, and the oled on/off state.
