In iOS 15.1, URLs containing Universal links is not working correctly on mobile safari.

My app has associated-domain to activate universal links.

In iOS 15.1 or higher versions, browser-back is not working correctly in the domain. Mobile safari doesn't save scroll-position after going back to the domain's URL.

It works correctly in the following condition.

  • iOS 14.x or iOS 15.0
  • removing https://<fully qualified domain>/.well-known/apple-app-site-association

Universal links may cause the problem.

Many iOS15.1 and iOS15.2 users is inquiring us about the same problem.

Is it bug of iOS?
