    I'm seeing this "unknown error 11503" when updating apps in iTunes on a Windows 10 PC.

    Anyone else seeing this? Any idea how to fix this?

    Rant on: How can an error be "unknown" when someone has assigned an error code to that error? This reminds me of sloppy Microsoft programming

    Try either signing out of iTunes and then signing back in or reinstalling iTunes to see if that helps.

    I tried signing out-in earlier and it did not fix it.

    I noticed that I was having issues updating apps on my device as well. I figured it was something on Apple's back end.

    The problem has fixed itself. iTunes seems to be working normally this morning.
