Rick, I got the same behavior as you, on Android. I was getting a 404 on the site that I had already set up (I think the 2nd of the 3 listed). I deleted that, searched, got 404s with the first two, 3rd one sat there and spun until I logged in, now things are back to normal. I'm not sure if that's very user friendly, people might not know that they need to log in. Is there some kind of configuration setting somewhere for anon's?
