LG TV - Turn on stopped working on this update

I use the following switch to control my LG TV

- platform: template
  switches:
    tv_tiago_lgtv:
      friendly_name: 'TV Tiago'
      value_template: "{{ is_state('media_player.tv_tiago', 'on') }}"
      turn_on:
        service: media_player.turn_on
        data:
          entity_id: media_player.tv_tiago
      turn_off:
        service: media_player.turn_off
        data:
          entity_id: media_player.tv_tiago
      icon_template: >-
          {% if is_state('media_player.tv_tiago', 'on') %}
            mdi:television-classic
          {% else %}
            mdi:television-classic-off
          {% endif %}

Everything worked fine until the last update. Now, only the turning off works.

Any ideas?

Thank you!
