When The Assistant is open in iOS Safari and the address bar is hidden, the toggles at the bottom of the page are very, very difficult to access as they overlap with the normal 'swipe up' bar. This is especially prevalent if you install the app as a PWA to the home screen. Screenshot attached.
The easiest reproduction is by adding The Assistant to the home screen, as that will always hide the address bar; however, any time the address bar is hidden, this is an issue.
Moving the toggles up by 10-20px (maybe more, I'm no front-end guy) should make them much more accessible on iOS.
