Unfortunately I’ve faced a problem that it’s not possible to edit the articles in Ukrainian. My app is in German language and the only thing I see when I press on “edit” on an Ukrainian language article is the phrase “Loading content...” (or smth like that - in German “Lade Inhalt...”) and nothing else happens. Whereas the same articles in different languages (German, English, Russian etc) can be easily edited.

Have confirmed that this is happening. Note that title descriptions can be edited, but no content.
This is not a problem on the Android app.
