I faced such a problem, cloudflare changes the interface (and functionality) personally, the new form of addition is not convenient for me, since I have to perform unnecessary actions due to the fact that I need to change my IP, I have to go into settings, DNS, and so on, when in the old form it was all done step by step and during one initial site setting
You can’t go back to the old interface, but if you’re looking for an easy way to add new zones, that doesn’t change even if/when the dashboard changes, check the API:
