Has anyone else been having this problem? I open up iTunes and it says I need to log in because "Your iCloud session has expired". I put in my ID and password, hit ok, then it says I need a verification code. So my iPhone gets a notification and a code, perfect. But now what? There's no additional dialog on my Mac. No place to put the code. What do I do? I tried restarting and logging in and out of iCloud.
