I have a Mac running Yosemite (DP7) and my iPads running iOS 8 GM. It seems the iPads can talk to each other and sync, but going between my iMac and the iPads is intermittent at best. Forgive me if this is a known-issue, but I'm a little confused. I tried all I could think of - reboots, signing out of iCloud, etc. Is there something I could be missing? The particular apps I'm trying to use are Mindnode Pro, Spectrum and Byword, if that matters. Thanks!
