Cold start deep linking still broken (redirects to Home instead of Target URL)

When opening a push notification on a cold start (app completely closed/killed), the app fails to open the targetUrl. It drops the target page and loads the Home page instead.

Expected behavior: App opens directly to target URL (e.g. /chat/123/).
Actual behavior: App opens to root / (Home page).
Environment: Rebuilt with latest Median updates a couple of days ago. Still happening.

Is there a specific native config or handler needed so the initial launch URL isn't wiped on cold starts?
