Hi,
Using Ver. 4.11.1, after upgrading from 4.7.2 to 4.11.1 and testing every step, the child nodes in 4.11.1 will not publish in 4.11.1, the notifier comes with an error that the parent not is published. After downgrading to 4.10.1 the published of child nodes works again. There is no error in the Umbraco log.
