I was auto-approved for a publisher but one of their books is showing up as "declined", can I still access it?

If you requested a digital review copy or audiobook from a publisher before they auto-approved you, your pending requests will automatically be approved after you are auto-approved.

If a request was declined, then this status will remain even after you are auto-approved. The only way to override a Declined request is by receiving a widget invite from the publisher for that specific book - if you are in contact with the publisher, then you can certainly request this.
