MQTT cover's retain flag

Configuration
1

Does the retain flag only apply to messages that HA posts to the MQTT server? I’ve set mine to true and still getting ‘unknown’ state after restart…

cover:
  - platform: mqtt
    name: Garage Door
    friendly_name: Garage
    state_topic: "garage/door/status"
    command_topic: "garage/door/control"
    payload_open: "OPEN"
    payload_close: "OPEN"
    state_open: "Open"
    state_closed: "Closed"
    retain: true

I think you need to set retain on the messages coming FROM the garage door sensor. That way when HA connects, it gets the latest state topic sent from the opener.
