We need WKWebView to use the ear piece as the audio device. Since it ignores AVAudioSessionCategory this is also not possible. If WKWebView has its own AVAudioSession it should be made accessible, how/where can we ask for that to happen ?

Same here Xcode Version 14.0 (14A309), app runs fine, will ignore warning. Would be nice to generally be allowed to let wkwebview live in background-thread.
