Footnote placed on the wrong page when figure placement is forced to page

Question

Whilst working with figures and footnotes, I noted a footnote placement issue. I have tried the different solutions listed in Using \footnote in a figure's \caption, which does not work for me as I have the figures on a separate page, forced to a specific location in the document using floatbarrier (From testing the issue is stemming from the page placement). The footnote appears on the page before the figures or after. Any ideas how I make the footnote text appear on the same page of the figure?

Code:

\NeedsTeXFormat{LaTeX2e}
\documentclass[11pt,a4paper,final]{memoir}
\usepackage{blindtext}

\usepackage{graphicx}
\usepackage{placeins}
% \usepackage{footmisc}

\usepackage{ftnxtra}
\usepackage{fnpos}
%\usepackage{stfloats}
\listfiles

\begin{document}

\chapter{Introduction}

\begin{figure}[p]

        \centering
        \includegraphics[scale=1]{red.png}
        \caption[A caption 1]{A caption 1}
        \label{fig:figure1}
        \includegraphics[scale=1]{green.png}          
        \caption[A caption 2]{A caption 2\footnotemark{}.}
        \label{fig:figure2}        
    \end{minipage} \footnotetext{reproduced from ... }   % is showed before figure page
