Start with the lbl:duckduckgo userstyle and reproduce the issue in Firefox using the Galaxy Note 9 device emulation. Inspect the mobile styling responsible for the top-of-page logo and verify the result at the affected viewport. Done means the DuckDuckGo logo appears once on mobile without changing the desktop presentation.
