Rather than every app needing to use a built in Web Browser Google developed a built in system and should ensure greater functionality. The Webview is a piece of code and the Developer only needs to add three short lines of code, ask for permission to use the Internet and open web content with a few more lines of code. Therefore benefits both Developers and users, however if Bugs not detected before updates rolled obviously this has consequences. However Google was pretty quick in releasing a fix, even if it may not be straightforward for everyone. see more on the dedicated thread for fixes.
