First time using Lens today to try to save a business card to contacts via OneNote. I can save to photos, save to Word, Save to OneDrive, but I try to save a business card to OneNote (Contact + Image), and I get the error "No network connection The device isn't connected to a network. Please connect to a network and try again." I'm connected to the network, I can add notes in OneNote and they sync to the cloud and to my computers. :-( Apple iPhone iOS 11.4.1, Office Lens for iOS V2.15 (180707).
