I have converted my HTML to masterpage and published a major version of it. When applying master page using design master page, I change the site master page to my newly converted masterpage and the system master page to seattle.
However the master page does not get applied to site. When changing the system mp to custom mp the mp gets applied. This also changes the layout of the admin pages(like site settings, contents,etc).
I do not want to apply my master page to site admin pages. Kindly help!
