URLs like https://meta.m.wikimedia.org/w/index.php?title=Main_Page&veaction=edit don't open VE. If you remove the "m." from the URL, it does work.
I think this is because the code handling veaction lives in DesktopArticleTarget.init.js and doesn't run on mobile. This breaks the useve=true functionality in <inputbox> on mobile, see e.g. https://meta.m.wikimedia.org/w/index.php?title=Grants:IdeaLab/Inspire&oldid=17677561
