How to write the notice of canceling the meeting because the chairman has something to do?

The notice of canceling the meeting due to the chairman's business reasons can be written as follows: due to the chairman's temporary change of plan, the scheduled meeting is cancelled and the time of the follow-up meeting will be notified separately. Please forgive me for the inconvenience and thank you for your hard work! This way of writing is clear and easy to understand, indicating that the chairman has something to cancel the meeting and greet everyone politely.
