I can't find "On My iPhone" in locations in Files
I was trying to save a attachement from "Mail" to phone storage but in "Save to Files --> On My iPhone" is not highlighted. It's allowing to save to iCloud or Goold Drive but not iPhone storage.
Then I went to check in "Files" app, there is no "On My iPhone" option at all in locations even after edit. Please help. (iOS 11.2.6)
