Disable all in-app browsing while keeping Chrome as default browser
You need to know this before disabling all in-app browsing,
In-app browsing is a required component by built-in requirements in order for web functions to render properly, as described by Google:
Android WebView is a system component powered by Chrome that allows Android apps to display web content. This component is pre-installed on your device and should be kept up to date to ensure you have the latest security updates and other bug fixes.
So there may be a chance that if you disabled in-app browsing and the Android System WebView, while Chrome as the default web browser, some web components may start failing to function properly.
