@Engineer The content I am trying to copy is text. For example, when using Google Translate (https://translate.google.com) within WKWebView, I translate a piece of text and then click the web page’s copy button. Although the webpage indicates that the copying was successful, there is actually no content copied to the clipboard. This functionality works as expected on both iPhone and iPad; however, it fails when running through Mac Catalyst.

This issue occurs on many websites, not just the one listed. However, the copy functionality is available on some URLs. I've attempted modifying the UserAgent without any success. webView.customUserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.5 Safari/605.1.15"
