I have created a business account and trying to claim my website but it's showing "
Sorry! deltaheatedvest.com has already been claimed by another user." but I didn't claim my website ever before. Can you please guide me how can I fix this issue and claim my website best heated socks so I can create my pins easily Thanks!
Since you have owned the domain since July, 2020, either the previous owner was on Pinterest or someone else has claimed it.
Your first step is to open a support ticket so someone who can see the registration can clear the previous claim.
