They’re having issues with the asset store at the moment. I’ve had trouble getting assets to show and when I tried to log into my publisher account it said I wasn’t a registered publisher. I was able to get back in though a little bit ago, though a few things were still wonky like comment styles not loading properly. I sent them an email earlier this morning and I think they are working on the issue.
I’m getting the exact same issues. I saw some tweets from the asset store account from about when these posts went up saying the asset store was back up, but I’ve been unable to log in to it all evening.
