This message keeps coming up every couple of minutes in iTunes 12.3 and I'm not sure how to fix it... anyone else having the same problem / know how to fix it?
Alas, the Windows version of iTunes 12.3 is causing this problem, too. I believe Apple is now aware of this and may issue a patch to iTunes itself to fix the problem.
Good news! It appears Apple has fixed the problem without having to download a new version of iOS 9.0 or iTunes. Sounds like a server problem on Apple's end.
