We have been using “login with amazon” with the scope “cpc_advertising:campaign_management” for some time. And it really worked until recently. But now, if someone tries to use “login from amazon”, we get the error “unknown area was requested”. How could this happen? We have recently migrated our application from Seller Central to Amazon Developer, could this be the cause of the problem?
I also asked about it using “contact us” from https://developer.amazon.com/ where I wrote the client_id and the entire link that causes the error.

Did you ever get a response to this?
Thanks for reaching out.
