For the past month, I've been logging into my Webmaster account, only to see that 90% of my sites are unverified, with a "WARNING" in text next to all of the sitemaps. If I refresh the page, most (but not all) of the verification warnings go away, but the sitemap issue is still there. Is anyone else having this problem?! I can't imagine that it's just me. Most of the sites haven't even been updated in the past month or two, so there's no way that there could be a sitemap issue. Not only that, but the verification was never undone, either....
