​@swmartinez Could you uninstall and reinstall the extension, then follow the setup instructions here?

It worked when i went to the login on app.gohighlevel.com instead of the whitelabel custom domain of the agency I am using.

Hi,

I can confirm that the correct way to start the login flow is to start at app.gohighlevel.com.

We are working on an update to make it work when you start from your whitelabel domain.
