If you are running both website and apps for serving same content/service, then your app must be able to handle deep linking / universal links properly. It should be able to open your website’s link in app, if app exists or in browser, if app doesn’t exist. For doing this in react native iOS app, one needs to do some configurations in react native app as well as on website.
