An issue appeared today on my app where when users try to link their youtube brand accounts through the google oauth flow, they get stuck after agreeing to the terms and conditions. They are not redirected back to the webpage and are stuck on that page. It was working fine till yesterday and still works fine if users link their personal youtube accounts.
In the browser console, I see the following error: "Error code = 103, Path = /_/OAuthUi/data/batchexecute, Message = There was an error during the transport or processing of this request., Incomplete XSS header at end of request (HTTP Status: 401) (XHR Error Code: 6) (XHR Error Message: ' [401]')"
Any help on this will be appreciated
