It appears that Google is working on releasing a new version of the Google AdSense Homepage, and possibly even a new version of the Google AdSense reporting and user information page. However, as of right now, I am unable to log into my Google AdSense account, as everytime I try to sign in, I’m redirected back to the new default Welcome to AdSense page.
The sign in page is no longer part of the AdSense homepage, you click a link that reads: Already using AdSense? Sign in » but upon clicking and signing in, users are currently being redirected back to the main AdSense homepage.
I hope that Google has something good in-store for us! I’ll keep my fingers crossed.
