Apple ID account
On my current device, I signed out of my main Apple ID account and created a new account. I decided to not use this new Apple ID account and log back into my main Apple ID account. But every time I try and do so, it says that it isn’t available. The account that I am trying to sign into is currently logged in with another device of mine too. Why is it not letting me sign into that Apple ID and what can I do to sign into it with my current device.
