Shopify app live issue

Hello everyone,

I hope you’re doing well.

I’ve developed a Shopify app locally and, after completing development, deployed it to a live server. The app uses a custom MySQL database.

The issue I’m facing is that when I install the app on a Shopify store using the custom install link, the installation appears successful, but the session table is not being updated with the new access token.

I would appreciate any guidance on what might be causing this or how to resolve it.

Thank you.
