Customize not updating

It seems that your configuration.yaml doesn’t properly include customize.yaml
Changes made here won’t affect your configuration.
this message was in customize in HAssio.

it used to work for me, something went wrong with the last hassio updates.
I have customize configured just like before.

I tried customize: in config file manually then tired from hassio what should i do.
my overview is fulll and i can’t hide the entities

It’s working for me on the latest version.

What is the exact entry for customize: that you have in your configuration.yaml file (post your code, correctly formatted)?

What is the file name of the file that your customisations are in?

What does the first few lines of your customisation file look like (post your code, correctly formatted)?

Originally I have the customize entered manually in the config file and was working before the update, or what ever I did!! Next I tried using cutomize in a different file and calling it from the config.
Original like this:
customize:

   switch.kill_switch_net:
    friendly_name: Camera reboot
    icon: mdi:power-plug
    
   switch.hdmi_1:
    friendly_name: HDMI 1
    icon: mdi:video-input-hdmi  

   sensor.hallway_nest_protect_smoke_status:
    friendly_name: Nest Smoke Status
    icon: mdi:smoking-off
    
   sensor.living_room_thermostat_humidity:
    friendly_name: Nest Humidity
    icon: mdi:water-percent 

next method like this:
Customize: !include Customize.yaml

in the customize file I have this:

    sensor.fibaro_system_fgfs101_flood_sensor_alarm_type:
      friendly_name: FIBARO System FGFS101 Flood Sensor Alarm Type
      hidden: true
    sensor.fibaro_system_fgfs101_flood_sensor_temperature:
      hidden: true
    sensor.fibaro_system_fgfs101_flood_sensor_alarm_level:
      hidden: true
    sensor.home_eta:
      hidden: true
    binary_sensor.sensor:
      hidden: true
    binary_sensor.living_room_thermostat_fan:
      hidden: true
    binary_sensor.living_room_thermostat_has_leaf:
      hidden: true
    sensor.living_room_thermostat_humidity:

Does your file name start with a capital letter too? Linux and thus HA are case sensitive.

Also cusomize: should not start with a capital letter.

hi I found the solution.and may help others

if you put customize:` anywhere in the config file it has to be under Homeassistant:`
and make sure to be 2 indent and to add some kind of custom entity under that customize:

if you put customize: somewhere else in the config file and had 4 indent HA will compile with no error but when you reboot HA all the cutomize entity will not apply.
