Converting classic site to modern ui.

Copper Contributor

I'm able to create new pages using the modern UI. 

 

However, site contents and site settings are using classic mode.

 

I suspect it's the masterpage that's applied. Considering modern pages don't have a masterpage. How would I go about modernizing site content and site settings?

That's very strange...is your site customized in any way? If the anwer is no, you should see the modern experience for the site contents page and the site settings page
