Approve / Publish multiple items
Allow for multiple items to be approved / published at the same time.
Update 29 April 2020 - The Site pages library now includes a 'Publish/Republish' button in the library menu. If you select multiple pages with a draft version you can now publish all at once these from the library
you may not be aware that you can still access the old 'Manage site content' interface if you have Site Collection Administration privileges.
In your browser, add /_layouts/15/sitemanager.aspx to the end of your site address.
I'm not sure about approvals, but I was able to batch publish multiple pages (after I had updated metadata in the Site Pages library) and nothing untoward happened to my Modern pages.
I still agree that the Modern interface needs a control that allows the publishing of multiple pages.
I'd rather my content owners be able to publish their own pages and I want to make it easy for them when they have multiple new pages to release. I have better things to do than to do this for them.
