Universal Deep Linking with redirects stopped working from iOS 17

Hello Everyone,

we've encountered an issue with our iOS mobile application, particularly affecting users on iOS version 17. It appears that our universal deep links coming from redirects have ceased to function properly.

We've got quite a few marketing campaigns that send out promotional emails through an emailing system, which wraps our site's links inside their own. Obviously tapping these links does not open our app, instead directs the user to web mobile.

Older phones like iPhone X with iOS 16 still work properly.

We have checked domain association, and also when tapping direct deep link everything works properly. However, the issue arises specifically when users interact with marketing tracking links that redirect to a deep link. In this scenario, both Safari and Chrome fail to redirect outside of the browser environment. Instead, they execute an HTTP 301 redirection within the browser itself.

Is this something be expected from iOS version 17, is there a way to avoid this behaviour and still continue using marketing links with redirection?
