Hide Browser Nav not working in iOS 14.3

I was able to hide the browser navigation on the home page of my prototype by checking the “Hide Browser Nav (when launched from iOS home screen)” box in Generate HTML > Mobile Device. However, when I click a link in the prototype that opens another page in the current window, the browser nav reappears.

I can click “Done” or back to get back to the main prototype page without the nav, but I really want to eliminate the browser nav on all prototype pages.

Am I doing something wrong?
