Changing book cover > Likes and Comments

Hello,
I wanted to update my cover but for some reason it won't let me. My cover is updated on amazon.

Covers should not be updated, you can add an alternate cover edition for the new one.

Thank you, Martin. how would I go about doing this?

From the page showing correct ISBN or ASIN click on the button with three dots next to 'edit book details', this will give the option.

thank you
