A new permission in the owner profile allows owners to cancel their own reservation before the arrival date.

Both booking and cancelling from the owner portal

It was already possible to allow owners to book a stay for themselves directly in their owner portal. Now, they can also cancel it themselves if that reservation is no longer wanted. The only limitation is that cancellation is only possible before the arrival date; cancellations on the day of arrival are not accepted.
Cancelling can be done directly from the overview page in the owner portal, using the button behind the future own reservation listed there.

If an owner cancels their own reservation, you will be notified of this in a reception message.

Setting it up in the owner profile

To ensure that your owners can book and cancel their own stays, go to your owner profiles and edit them. See that the owner permission that allows owners to make reservations is checked, and then also check the new permission that allows owners to cancel.
Updating the owner profile applies the change to all owners with this profile.
