I have an issue with Mailchimp setup

Site: https://paulpetchstockphoto.com/

Same issue, I have entered multiple API keys from different MC accounts and no lists load.

I have tried generating an app, but no luck either. I have entered the key in the playground and it is working correctly.

Please resolve ASAP

Update. Multiple emails. Login passed to Thad. Nothing. Followed up and no response. Still does not work.
