We received this through the Wikimedia apps pages on Mediawiki:
When I use the Wikipedia app (on Android) there is a bottom-border menu that includes a hamburger button labelled 'More'. When I select this, it presents six options, starting with my own user page, and finishing with 'Donate'. Of these six, four are wikilinks that open in the app, and 'Donate' is a URL since it opens a page outside Wikipedia. What annoys me is that the first link, to my own user page, is also a URL, so it opens in a browser. Why is this? If I want to use the browser interface, I can decide that for myself, but if I've chosen to use the app, why would it send me over to the browser?
I know that can get there via my user talk page in one extra click, but...
Not a major issue, just a persistent niggle.
