Probably after the update that's going to happen at 11am.
You did notice that it's currently referring to a different update than it was yesterday, right?
I find it hard to complain about a notice regarding updates when we have been surprised by unannounced updates so often. This banner is something that everyone should notice and we should all appreciate it.
I could NOT agree more. Thank you for keeping us updated, it is not an inconvenience when it helps make the experience better for everyone.
