Hello! I'm trying to verify my website for my brand new Tarta business account but Pinterest says "Sorry! tarta.ai has already been claimed by another user." How that can be possible? Is there a way to see who has verified this site on Pinterest before? As far as I know I'm the first owner of the domain. I don't think anyone else has verified it on Pinterest before.
I'm trying claim by uploading HTML file and adding TXT records, none of that works.
