Questions and discussions about using the Shopify CLI and Shopify-built libraries.
Upon installing the app, I am being redirected to a non-embedded version. When accessing the app from the installed apps list, the app is redirecting to the embedded version. Using Codeigniter framework and below specifying the corresponding code.
I'm not familiar with the CodeIgnitor framework or PHP but please ensure you're following the oAuth path that is mentioned here.
It does sound that you're on the right path from the docs :
"it is critical that the initial OAuth redirect to Shopify occurs at the parent level, escaped from the iFrame".
Check out the docs for next steps.
