Hi, @daisyweber !
Just to get some more context on how to help, can I ask where you got the verification code for your website? There are steps here you can follow if you wanted to verify you are the site owner with Google, I’ve linked a video below! It’s important to remember that your storefront password needs to be disabled for your site to be crawled and verified, if your password is still enabled the authentication process will be blocked.
If you wanted to verify your site another way apart from Google, could you let me know what steps you are following so I can get a better idea on how to help? Thanks!
