I’ve noticed that the mobile app supports links that are redirects to sections. That’s great, although the Table of Contents displays the redirect page title at the top, which is bewildering—but not the main issue I’m reporting.
“Pipe links” to specific sections within other articles just link to the top of the other article. That seems unfortunate since these are used in some specific cases.

I’m using version 6.8.1 (1815) of the app on iOS 14.6 (18F72).
