TestComplete is unable to detect any element for desktop application screens developed using Microsoft WebView2. TestComplete must support Microsoft WebView2.
Its still the case for us altough the latest 2 versions should have working web view 2 support
Have you contacted support? Just sent them a sample of WV2 page, where they can reproduce the problem. My guess is, that there are still some edge cases, where the current WV2 support need to be refined.
