Upagrade: MacBook Air Early 2014 > MacOS 10.15 Catalina

I follow the steps carefully.

> Upgrade now >>> Mac App Store Preview, with

macOS Catalina / Apple / Free

at top and screenshots below that.

But there is nowhere to click to move on from this screen.

If I click on the Apple link (just to the right of the Catalina icon and below the text "macOS Catalina",

it loops me back through the promotional material and finally back to this screen.
