I can confirm the issues with iTunes Store when attempting to sign in; I get the same errors described in this post. However I can still view the contents of the Store, but that's pretty much useless since I can't purchase/download anything. I have updated the list to reflect this new information:
As always, thanks so much to everyone for the additions to the list while I've been away, and sorry for taking so long to finally get around to updating it. With that said, here's the Summary of Changes this time:
