cannot sign out of Icloud on one of my devices
I have 4 devices all signed in with Icloud 4 are using my wife's credentials. I want to sign her out on one of them as it is primarily my device and I would like to link my icloud credentials. No luck. I have been through every possible combination of steps to deauthorize including getting codes from other devices.
Each time I am left with the message that icloud is waiting for approval from another device, but that is simply not true.
each time i am told that I have entered my security code too many times and that I can verify through apple, clicking this link takes you to an apple information page, not helpful. within the sequence of steps, I am also given the option to retrieve a code from another device, which I do, and the loop regenerates, nada.
Any tips are appreciated...
