Yeh this is a known problem. The lead is usually used to explain how to use the talk page but the templates are rarely mobile friendly or if they are they push down topics making it hard to see them. As in the example you post sometimes topics dont have headings which we can't detect easily programatically.

Ideally we would include the lead somewhere in the talk overlay but possibly underneath an information sign.

This will need a lot of design input so pushing to Alex.

@ovasileva @Jdlrobson are we tracking this elsewhere already?

@nray @alexhollender seems relevant given our current sprint work.

Clicking "read as wiki page" reveals that content https://en.m.wikipedia.beta.wmflabs.org/wiki/Talk:Wikipedia_Asian_Month#

However pages like https://en.m.wikipedia.beta.wmflabs.org/wiki/Talk:Wikipedia_Asian_Month_2# are misleading, when "read as wiki page" shows there actually is some kind of talk topic. Could we change the language somehow to make this less confusing?

I agree it's confusing as is. I'm not really sure what language change would make it less confusing though without doing more work to parse the html to see if there is content there - All I can think of rn is something like 'No sections found on this page, but click on the "Read as wikipage button" and you could win' which is obviously horrible.

We could probably do some more work with the ParserOutput object to see if any content is present. I'm not sure what the best languages would be if content is found that is not a part of a section though

Just to give you a heads up. On svwiki there is now discussion on bot editing in a dummy header as a work around of this problem since the issue seem to have so low priority that it will not get solved quick enough. 40 000 talk pages are estimated to get such an edit.
