LaTeX Appendix in wrong order

Question

I am writing my thesis in LaTeX, document class article. I experience the following issue in adding an appendix to my thesis.

\documentclass[11pt,a4paper]{article}
\usepackage[titletoc]{appendix}
\begin{document}
    \input{9-Appendix.tex}


9-Appendix.tex
\begin{appendices}
\section{Tables and figures}\label{appendix:A}
\subsection{...}
\begin{table}[h]
\resizebox{\textwidth}{!}{%
\begin{tabular}{@{}|l|l|l|@{}}
\end{tabular}%
}
\caption{First table caption}
\end{table}
\pagebreak
\begin{landscape}
\subsection{...} 
\begin{longtable}{lllllll} 
\caption{Second table caption}
\label{tab:my-table}\
\end{longtable}
\end{landscape}
\pagebreak
\begin{table}[h]
\scriptsize
\centering
\resizebox{\textwidth}{!}{% 
\begin{tabular}{llll}
\end{tabular}%
}
\caption{Third table caption}
\label{tab:my-table}
\end{table}
\begin{table}[h]
\scriptsize
\centering
\resizebox{\textwidth}{!}{% 
\begin{tabular}{llll}
\end{tabular}%
}
\caption{Fourth table caption}
\label{tab:my-table}
\end{table}
\begin{table}[h]
\scriptsize
\centering
\resizebox{\textwidth}{!}{% 
\begin{tabular}{llll}
\end{tabular}%
}
\caption{Fifth table caption}
\label{tab:my-table}
\end{table}
\begin{table}[h]
\scriptsize
\centering
\resizebox{\textwidth}{!}{% 
\begin{tabular}{llll}
\end{tabular}%
}
\caption{Sixth table caption}
\label{tab:my-table}
\end{table}
\section{Historical series on ...} \label{appendix:B}
\par Text
\end{appendices}
\end{document}

Now the issue is that my appendix B is appearing somewhere between the first/second subsection of Appendix A, instead of right after the last subsection.

Any ideas on how to solve this? Using \begin{subappendices} \end{subappendices} does not resolve the issue.

Answer 1

Just for completeness, this now runs:

\documentclass[11pt,a4paper]{article}
\usepackage[titletoc]{appendix}
\usepackage{pdflscape}
\usepackage{longtable}
\usepackage{float}
\begin{document}
\begin{appendices}
\section{Tables and figures}\label{appendix:A}
\subsection{...}
\begin{table}[H]
\resizebox{\textwidth}{!}{% use resizebox with textwidth
\begin{tabular}{ l | l }
  {\bf Symptom} & {\bf Metric} \
\hline
This is a & rather small table
\end{tabular}% close resizebox
}
\caption{First table caption}
\end{table}
\pagebreak
\begin{landscape}
\subsection{...} 
\begin{longtable}{lllllll} 
Some & really & really & long & text & goes & here\
\caption{Second table caption}
\label{tab:my-table}\
\end{longtable}
\end{landscape}
\pagebreak
\begin{table}[H]
\scriptsize
\centering
\resizebox{\textwidth}{!}{% 
\begin{tabular}{llll}

\end{tabular}%
}
\caption{Third table caption}
