There is no option to mark edits as minor in mobile source editor. I can't even see changes ( "Show changes"). The "edit summary required" setting doesn't work on mobile too. Please fix these issues. IMO, mobile source editor needs urgent work.

What device are you using?
Chrome Dev For Android 78.0.3902.3 Android Nougat ZTE. The visual editor on mobile has the option to show changes, mark edit as minor. But in the source editor, all I can do is edit the source, click "Next" and give edit summary and then "Publish" page. I get to see a preview of what I changed but I can't see the preview in wikitext.
like what kind of edits i was redirected to that page you cant see what i'm -texting sorry small screen .
