“Access blocked: Authorization Error”

Firstly, the plugin works seamlessly on the first website we tested and installed it on…. Now that I am setting it up on the second website we need it for we’re running into an Authorization error. This error occurs in a regular and incognito browser when I try to “Login with Google Sheets”. I need someone from support who is willing to work with me to address the issue. So far via the email support I was offered a refund, credentials to some random Google API (which I did not put into my site!), and suggestions to remove and re-add the connection on both websites…
