I'm not able to do handoff running either Pages, Numbers or Keynote on iPhone 5S running iOS 8.1 and Yosemite. Everything else works in terms of Handoff, i.e. Mail, Maps, Contacts, Safari, etc. I've done multiple reboots and sign-offs/ons on both ends to no avail. Is there some known Handoff compatibility issue in Pages, Numbers and Keynote? Has anyone been able to successfully use the Handoff in these three apps?
