Sorry I don't have any help to offer, but I just wanted to add that you're not alone, I'm getting the same messages on PC. This happened to me a couple of months ago around the time that 3.0 came out. It happened for several days but slowly got better. The problem went away until recently, I saw the message on four separate occasions last night.
I don't think there's anything we can do, it seems to be a server-side issue.
