Previously as a network admin i was able to go to the dashboard of any blog, see the my account button, click on it and view the payment page for a client.
This was useful in the event that the client wanted me to enter the credit card for them over the phone.
Now in order to do that I have to add my user name to their account and then i will have access to the page and see the my account button.
Let me know if this is a bug. Thanks
