I discovered on Friday that I could no longer move pages withint the SitesPages library on Modern sites.
I have turned on folders on the library and up to last Thursday 24th Oct 19 was able to move pages between the folders by selecting the page and then hovering over the correct folder in pages library via the breadcrumb.
But when I do it now I get a denied icon (see screenshot).
I have made a solution temporary using a flow, but it is not ideal as the relative links to that page via quicklinks or the menu break when the flow moves the page.
Has anybody experience this issue or read anything about Microsoft working on the pages library functionality?
