My sample app request user agent as <Mozilla / 5.0 (iPad; CPU OS 13_0 like Mac OS X) AppleWebKit / 605.1.15 (KHTML, like Gecko) Mobile / 15E148> on WKWebView, iPadOS 13.Then response received via didFinishNavigation, user agent has changed to <Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15) AppleWebKit/605.1.15 (KHTML, like Gecko)>.It doesn't happen if witdh of WKWebView is less than 375.Is this a Bug or New Specification?
