A client sent me a Klaviyo invite but I am never able to launch the app from their Shopify store. I have access to their store’s Products, Themes, and Apps. I have deleted all site settings (cookies, etc.) and logged in fresh. I have had them resend me invites. But every time I click the App from within Shopify admin I get this error:
Access to www.klaviyo.com was denied
You don't have authorization to view this page.
HTTP ERROR 403
I’m at a loss and frustrated that I can’t help my client.
