iOS universal links are working only with Safari default browser

[AlexPopaUpcode]

Describe the bug

We have an app that has both a web and a mobile version. After registration the user receives a URL via email that will verify the email and auto login the user. We want to achieve the following: if user doesn't have the app installed then he will continue to the onboarding on the web app, but if the mobile app is already installed then we want to auto login the user and continue there.

On iOS the universal links are working only if the default browser is set to Safari and the user chooses the default browser to open the link. If user chooses another browser from the list, or the default browser is chrome, then the flow will continue in the web app instead to the mobile app.

Note that there is a redirect going on. When user taps on URL received via email, the browser opens, a request is sent to the backend to mark the registration completed (to confirm the email), then a redirect is performed. In the new redirect there is the universal link we want to capture.

This package has no direct relation with web browsers. Are you sure that you're chrome browser has been setup to open links with applications? (I don't use Chrome, but on Firefox there's such of preference)

I believe there is no such setup there. In Safari browser tap and hold on a URL shows more options, 2 of them are: Open in Safari and Open in MobileAppName. Pressing the Open in MobileAppName opens the mobile app, but pressing first one will open the URL in browser and not the mobile. Maybe this is because of user choice, but I want the default behaviour to be Open in mobile app instead of browser

There is nothing we can do here. This is external to this package even to your app...
