Problem : Correcting child page restrictions that have diverged from the intended audience over time.
The structure in question has been maintained by multiple different people over time and though the parent page has the correct restrictions, there are dozens of child pages with restrictions slightly different to what they should be and rather than manually correct via the web UI, I was wondering if there was a programmatic / administrative solution where all child pages could have the parent page restrictions applied, or inherited - similar to Bitbucket repo settings inheriting from the parent Project?
