If you have a Google AdWords MCC (My Client Center) account you may be having difficulty heading home.
If you are within a client and you are wanting to go to the home page view of that client, clicking "home" will take you back to the MCC home page, not the client home page.
One top AdWords advertiser said in a Google AdWords Help thread:
Every time I click the home tab in either account that I am managing.. I keep getting sent back to the MCC overview.I've tried clearing cookies and cache.. I;ve tried two separate browsers Chrome and FF (both up to date versions)
This is really driving me nuts :-/
Google confirmed the bug and I personally have confirmed the bug on my side as well.
Bindu from Google said, "the good news is that it's not just you. It's a lot of advertisers, in that, this is a known issue that we're working to fix. And I'll ensure I post updates once the fix happens."
