This is a serious issue. There is no way to communicate with iOS app users, as far as I can tell. Various editors are blocked for "Communication is required" when we can't even communicate with them. There is a link to a user's talk page, but it's buried within the settings, and there's no reason you'd look for it if one didn't already know what a talk page was and that they should frequently visit it.
