Changes made to your listings on the booking channel (such as a listing being unlisted, a new listing added, a listing deleted, or a change in regular check-in/out time) will be reflected on Properties.
On occasion, however, you may need to see these changes immediately.
To do this, you can re-sync your listings:
Click on Connected accounts
Click on the Edit button to the right of the connected account that has the listings you wish to re-sync
This will automatically trigger an operation that will be performed in the background and may take a few minutes. If you have added a new listing, you can find this directly on Properties (under a green background to showcase this new property).
