Same behaviour observed on other pages with Wikidata updates; when they are clicked on the Android app Watchlist it displays the latest Wikipedia update instead.

(to preface: "wikidata edits" is a new addition to the watchlist screen in the app.)
There seem to be a couple of issues here:

The app uses an API query to get a list of change events that correspond to your watchlist. However, in the case of Wikidata edits (i.e. external watchlist events), the API actually doesn't seem to provide us with the necessary details to construct a diff link to the corresponding Wikidata entity. We'll need to put this in our backlog for now, until we figure out a different/better API query for getting watchlist events with all the necessary details.

The other issue (which we can solve) is that the app currently displays Wikidata edits in your watchlist by default, which is actually not the default on the web version of the watchlist. I don't believe this was intentional, and we should make the default state match the defaults on the web. This is likely to be a source of confusion, so we'll update the defaults in our next release.

True; I don't expect to see Wikidata updates on my watchlist, and had to enable them to follow up this issue. But what about the people who use mobile watchlist and expect and want to see Wikidata updates there? Can they be warned, and will enabling Wikidata watchlist items affect mobile as well as desktop?

You can enable Wikidata updates by going into the Filter selection (tap the "filter" icon in the search bar at the top of the watchlist screen). They will simply not be enabled by default.

will enabling Wikidata watchlist items affect mobile as well as desktop?

Your watchlist filters in the app are separate from your preferences on desktop.
