I hope this is the right place to ask this, we have a iphone 4s and a iphone 5c. My dad recently bought another iPhone 5s, and now all 3 are on 1 apple ID. I shifted my mom's and sister's phone to another apple ID, to give dad exclusive access to his ID, however, when I try to facetime with any of the other phones, it says 'connecting' forever. I tried the advice here, but to no avail.
Would appreciate any advice, should we just take it to the apple store?
