The article you're reading is part of a whole knowledge base, hosted online so it can be updated without an app release.
A search box over every article covering the app, plus a ? button on most pages that opens the article for exactly that screen. Reaching Help from a specific page (via its ?) jumps straight to that page's article instead of the search landing.
If you open Help with no connection, it shows a saved offline copy instead of going blank — a banner reads "You're offline — showing saved help" so you know it might be a step behind the live site. If you didn't find an answer, Send feedback from About & support reaches the developer directly, and tells us what to write next.
