Hi,
First, the setting "Block all third party cookies" is disabled and my Google account is authorized to work with Box. I've uploaded a Google Sheet to my Box account, but when I try to open it, it requires me to sign into a Google Account. However, when I press sign in, I get a Google 400 error and says "The server cannot process the request because it is malformed. It should not be retried." What can I do?
