Shopify App seems to redirect to LocalHost

Hi there,

When installing the custom app we made on Shopify, we get redirected to localhost the first time around and keeps doing that unless we change the localhost url in https://localhost:3000/?hmac={hmac}&shop={shop}&timestamp=1622137332 to our hosted url. I also can’t seem to access the app when on different browsers and it seems that I need to install it again for it to work. What is the problem with that?

Even my redirect uri contains the localhost which makes me unable to install the app if I don’t change it to the proper URL link
