I can't get it to work. I'm logged in with the same iCloud account on my Mac Mini and on my iPad Air. I have the latest Yosemite beta and latest iOS 8 beta. Bleated is active on both devices, and I can easily share files with Airdrop. But I never get the Handoff app down in the dock on my Mac. I've tried Maps, Mail, and Safari. I've also checked in the General settings on both devices that Handoff is enabled.
What could be wrong?
