Accidentally hid controls (mobile)

[Itsn]

I somehow hid the panels that have the series title, chapter plumber, and controls such as zoom and fit to width. I looked in the settings menu on my profile and saw no way to show it. Double tapping showed a header, but all it had was search, the home page, and browsing my follows.

How do I get the controls to display again?

Not entirely sure of what you describe, the fit to width is in the reading settings, quich setting in the reader sidebar, tap the center of any chapter image to show it, maybe the other is the Header Hidden setting and Progress hidden?
