New post titles aren't saving for the page title and URL
The page URL no longer automatically uses the post title is due to the SharePoint Online “Banner” title area update rolled out in 2024. This update decouples the page’s visible title from the file name to allow more flexible layouts (including no title banner or multiple banners) and improve accessibility

The new design requires authors to set the page title explicitly (either on the page or via the command bar field). The system will generate the file name from that title only the first time the page is saved. And in some cases this auto-generation doesn’t occur, leaving a default “Page#.aspx” name
