I have an iPhone 7+ latest iOS and have one drive installed. The app works well and syncs happily between all my devices. I however can’t get it to show up in the locations of my iOS files app. The files app only shows iCloud Drive and iPhone content. Subsequently I can’t insert a one drive document into an email. This link explains my problem nicely but at point 5 ‘one drive’ isn’t an option to select nor can I add a new location or toggle one drive on/off. https://www.google.co.uk/amp/s/m.wikihow.com/Add-OneDrive-to-the-Files-App-on-iPhone-or-iPad?amp=1 please help!
