I am experiencing the same issue and my book is titled "AWS Certified Solutions Architect Study Guide". The list does not contain this title. What should I do? Thank you for your services.
I am expecting a similar issue. I bought the book CEH v9 Practice Tests. Followed the provided instructions and redeemed the access code. But whenever I try to redeem it, I get an error that the Access code I have entered has been already registered. Could you please look into it and provide me with a working access code to firstname.lastname@example.org
Thanks and Regards,
