I would like to remove the navigation dot in Beamer that corresponds to the title page. Here is a MWE. As you can see there is an empty dot for for the title page... how can I get rid of it?

NOTE I use the trick here Beamer navigation circles without subsections? to remove subsection navigation dots.

\documentclass{beamer}
\usetheme{Frankfurt}
\usecolortheme{dove}
\usepackage{remreset}
\makeatletter
\@removefromreset{subsection}{section}
\makeatother
\setcounter{subsection}{1}

\setbeamertemplate{items}[circle] 


\title{Stackexchange is great}
\author{John}
\date{\today}

\begin{document}

\begin{frame}[plain]
  \titlepage
\end{frame}


\section{Motivation}

\begin{frame}{A sample slide}
hello
\end{frame}

\begin{frame}{A sample slide}
hello
\end{frame}

\begin{frame}{A sample slide}
world
\end{frame}
\end{document}

Not sure if this is the best way to do it, but it seems to work:

\makeatletter
\let\old@beamer@writeslidentry\beamer@writeslidentry
\def\beamer@writeslidentry{%
  \expandafter\beamer@ifempty\expandafter{\beamer@framestartpage}{}% does not happen normally
  {%else
    \clearpage\beamer@notesactions%
  }
}
\makeatother

\begin{frame}[plain]
  \titlepage
\end{frame}

\makeatletter
\let\beamer@writeslidentry\old@beamer@writeslidentry
\makeatother

I just removed the two \addtocontents{nav} invocations from \beamer@writeslidentry.
