I missing WiFi sync in Android Beta.
WiFi sync is my favorit sync option between my iPad and my iMac. WiFi sync between iMac and my Android phone was fine.
Folder sync is so involved. :-(
You may be able to achieve something equivalent to WiFi sync by combining folder sync with the appropriate app or service, but you are correct that it will be more involved than simply setting up WiFi sync. I will pass on a vote for this feature from you to our development team. Thank you for the feedback!
