Answer the following question: Given this review: "No native calendar and contact sync (saying someone would need a 3rd party app for that is like saying you need to install Internet Explorer for HTTPS support in Google Chrome...) Yubikey U2F doesn't seem to be working with this app but it does in my Chrome browser (No U2F support #796)." Would you recommend this app to a friend? Not at all, No, Maybe, Yes, or Definitely?
Answer:
Not at all
