My user A created an app in google appengine. I would like my user B to take over the billing. I then gave user B access to the project and made a payment from his account, but now he cannot change the billing settings. When user B clicks the "Take over billing" link but get:
"You do not have sufficient permissions to make billing changes. Your budget settings could not be saved. For help please contact support. "
The link to customer support just tells me that there is only support for premium accounts :-(
Any suggestions on how to let another user take over the billing?
