Dear Microsoft Team,

The author name located on top left corner of UI SharePoint page is linked with "authorbyline" property field.

However after updating this field via PowerShell script and in .NET code CSOM PnP, the change of author name does not sync to the SharePoint page.

It would be nice pragramatically updating the author name is supported in the next release.

This request would bring value to the business when migrating bulk pages from a third party intranet site to SharePoint Online so that instead of manually updating each SharePoint migrated page with the author name and publish it, instead a custom built migration script that I've developed could auto update author name on bulk migrated pages.

Thanks.
