facetime login an error occured during activation

Of course, when I asked why on earth they did this, she outright refused to give any explanation. After a full day on the phone with a tech support agent who berated me (she was getting paid to hear my complaints, I was wasting time and money well beyond the call, which itself was too long), and then waiting almost 4 more days (2 'business days' so the weekend did not count), some higher support group simply unlocked her devices and they've been good to go since. Doing that would then ruin her access to FaceTime and Messages on the iPad, but the iPhone was always good. In every instance, FaceTime on her laptop would accept the login but then ask about something in the keychain and pop back to the login screen without explanation (credentials were unflinchingly correct). I could get one of them connected to Messages, but then trying the other would throw them both in limbo again.

We wiped her iPad and MacBook Pro over and over for naught. It's not enough to pay top $$$ for their stuff, but to lock people out of their Apple ID (logging-into iCloud still works b/c they want it to, but not on actual devices where Y-O-U want it to work) without any notice and with a stupid error that is meaningless (as per this and many articles like it) is tortious interference, plain and simple. Oh, her Apple ID worked fine for their unwanted iCloud by itself, but Messages and FaceTime would throw everything into chaos and refuse to connect with any real/meaningful alert (they sure can spam the Apple ID email with every other thing, why not to report an issue that requires a call to Apple).

It turns out that Apple -surreptitiously and without any explanation- blocked her devices from connecting. Try again.' on every device, except her iPhone. My wife had this ridiculously useless error 'An error occurred during activation. Call Apple and DEMAND to know if the geniuses running their servers have locked-out your devices.
