That can't be true because the mobile version doesn't allow access to all of Wikipedia's functionality, such as talk pages, unless they've made some serious changes. (More precisely, I don't remember there being any way to get from an article to the article's talk page without editing the URL in the mobile version.)

This was fixed quite some time ago, there's now a Discussion tab/link on the mobile version.

Can you tell me you I can get there, e.g., here? https://en.m.wikipedia.org/wiki/Test

The work "discuss" does not show up in the source code, you can check "curl https://en.m.wikipedia.org/wiki/Test | grep -i discuss"

The discussion is called "talk" on the desktop version, but it is also missing on the mobile one. Or there is some javascript trickery going on, but I clearly dont get it.

Not sure why you're missing but https://i.imgur.com/llv2rtc.png

This is how it looks in my Firefox: https://imgur.com/a/x2Gl1Sj

And this is how it looks in my Chrome: https://imgur.com/a/LQ7pmH8

Ah, you're right.

You need to login and enable "advanced mode" in setting (in hamburger menu) to see it.

I see.

But this also means that every mobile user of wikipedia (I guess the majority now?) which is not logged in and enabled that feature (for sure the majority) does not even know about the discussion pages of wikipedia articles. This is super sad.
