Analytics error

Hi –

I’m getting this error when I try to set up google analytics. I don’t have any other analytics on my site, that I know of at least. How do I fix this?

Error: We’ve detected there’s already an existing Analytics tag on your site (ID UA-xxxxxx), but your account doesn’t seem to have access to this Analytics property. You can either remove the existing tag and connect to a different account, or request access to this property from your team.

Thank you
