i could gey my apple devices to sync icloud keychains , nor could i get them to turn off icloud key chain.
Solution: Reset icloud keycahin using forgot passcode option, it will reset the entire icloud keycahin and bring every thing back to the way it is supposed to be. approve all the devices using the one used to reset, and you are all good to go !!
You're my best friend. Seriously. I've read virtually every thread I could find on this issue, and this is the only thing that worked. Has been driving me bonkers since getting the iPhone 6 in September. THANK YOU!!
