Add messages to a booking sync problem

Hi,

if I post a message usinng API (https://api.lodgify.com/v1/reservation/booking/{id}/messages), the message is visible in Longify. But it does not have that green check icon 'The message was succesfully sent' and it is not synchronized with Airbnb etc.

It works only like if posted directly from chat window.

Looks like that 'subject' is not passed correcly.

call:
{
"subject": "test",
"message": "test",
"type": "Owner"
}

response:
{
"subject": null,
"message": "test",
"type": "Owner",
"is_replied": true,
"created_at": "2022-08-09T13:14:47"
}

thanks
