Hi @nettips,
Thanks for your comment.
You should no longer see the Black Friday banner in the backend. That said, we understand that the banner was annoying. Although it was dismissable, it was a bit buggy so last Thursday we released Yoast SEO v12.6.2 which completely removes the banner from the admin panel.
We apologize for any inconvenience this has caused you. You can also find our public apologies on social media through this link.
