It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The post mentions a flight cancellation by Singapore Airlines due to COVID-19, but it does not mention any maintenance issue or feedback related to a public flat house. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any of the other categories. The "explanation" field provides a brief explanation for why the post does not relate to the requested topic.
