Update: The error seems to have gone away on our devices here. Let's hope it stays that way.
The above picture may look familiar to many of you tonight if you've been trying to sync with Google servers. Many users are reporting seeing sporadic issues like the one above. You receive a notification about a sign in error with your Google Account, leading to the above screen, where following the "next" button seems to get you nowhere. The error is usually associated to an issue when you change your account password or your application-specific password for Google 2-step verification runs out, but we've ruled that out. This one's random kids.
We sure hope that Google is aware of the issue and is working to fix it. Let us know in the comments if the same is happening on your own devices.
