ios 6 calendar invite

Anyone having troubles not being able to dismiss google calendar invites after upgrading to ios 6? They just stack up now behind the "invitations" button. I can't accept or decline them. And the red notification icon above the app never goes away now.

I've got it all set up correctly according to this page: http://support.google.com/mobile/bin/answer.py?hl=en&answer=138740

And it worked fine before the update.
