We are using inline PhotosPicker introduced with iOS 17.0. The accessbility navigation using touch gestures work fine but the navigation through Keyboard doesn't work properly.
The tab/arrow based Keyboard navigation can't move from native app process to inline PhotosUI process or vice versa. This is logged as a high severity bug by our accessibility team. Please look into this.
