App specific password creation not working
After Friday's AppleID apocalypse (I know I wasn't the only one), where all my devices (2 Macs, an iPhone, an iPad, and my Watch) simultaneously locked my AppleID and I was forced to create a new password. Fortunately, this worked, even though my Watch kept prompting me for a while afterwards. Would be nice to have some clarity as to what happened.
So now I'm trying to re-enable my non-apple email and calendar clients. This requires, of course, creating a new app-specific password. I've tried on my iPad, one of the Macs (in Safari), and on my iPhone, and none are working. Errors vary from rejecting my new password (even though I've already signed in), to cryptic "this isn't working" messages. Fix this.
