If you are on mobile and you click a link to the desktop version, you get redirected to the mobile version. This loses the fragment identifier on the end.

For instance, open the following link on mobile (or in a desktop browser set with a mobile user agent header):

https://en.wikipedia.org/wiki/Paella#Valencian_paella

On desktop, it'll take you to the sub-section on Valencian paella. On mobile, it takes you to the article and doesn't take you to the specific subsection.

There may not be much you can do, although StackOverflow says that the Location header may contain the full URL with fragment. http://stackoverflow.com/questions/2286402/url-fragment-and-302-redirects

The location header could be parsed, and if it contains the equivalent desktop URL with a fragment identifier, the fragment identifier could be passed to the mobile version so the user can be taken to the right place in the page.
