Hey, hope you are doing well.
I developed Custom PHP App on shopify. One problem is when i try to install app from Shopify Partner account, app not load inside Iframe but until installation process is completed, but after complete installation when we close thw new window app starts displaying inside iframe normally when we open that app from shopify account. Did we have to include any Library or source code to display app inside or something else. Please share if you have any idea relevant to that like.
Regards
