An ECM illustrating the problem would be nice.

"\textt{Section Foo}" means that [[*Foo][Section Foo]] couldn't match
a headline. It can happen if there is no headline named exactly Foo in
the exported part of the buffer.

Below I provide ECM for LaTeX cross-referencing you requested, which itself summarizes the issues in the current export engine: We see that there are mix of results for different cases of heading title (i.e., \texttt{}, \hyperref[]{}, & \ref{}) and that only referring by custom_id results in a correct cross-reference. Note that, as mentioned in the list several time before, there is currently no way to customizing hyperref format using 'org-export-latex-hyperref-format' varible, which becomes obsolete now.
