Frozen Screen on Cold Start, but works after re-launching app

It is related to "cold-start" of application by link.

When user starts application by tapping on {ourapp}.app/... link - they will see frozen screen. This is fixed by re-launching the app.

If they launch app first --> then all links work perfectly until app is not shut down completely.

Also if app is installed from Xcode without Appstore - deep linking works even on "cold-start". When app is installed from Appstore - the issue with frozen screen is seen if open link on "cold-start".

In this way we understand that frozen screen is not related to Cloudflare settings, as deep linking works (app is opened on link's tapping). This is an issue with Median app code or settings which are unknown. We didn't find any useful information in app's logs what can cause this issue.
