Fix Kindle Purchase Availability

I have a Kindle e-book that is already live in my KDP dashboard, yet whenever readers in the United States, United Kingdom, Canada— or any other marketplace—attempt to buy it, they see a message saying the book cannot be purchased. I need this restriction removed so the title can be bought in every Amazon store worldwide.

What I expect from you:
• Log in (via shared screen or delegated KDP role) and pinpoint why the Buy button is blocked.
• Correct territory rights, pricing, and marketplace settings so all stores list the book as purchasable.
• Verify the change is reflected on at least amazon.com, amazon.co.uk, and amazon.ca.
• Provide a short hand-over note outlining exactly what you changed so I can replicate the fix on future titles.

If you have recent experience resolving “unavailable in your region” messages on KDP, this should be a quick adjustment. Once complete, I’ll confirm the Buy button is active, release the milestone, and leave a detailed review.
