Hit the same issue. I think it's a problem with the MapKit APIs that failed to get response from local data provider (Amap in China). Filed a ticket in Feedback. I would suggest you file another one to make the issue heared. https://feedbackassistant.apple.com/feedback/15544549

Hit the same issue. In my case, the request fails even when naturalLanguageQuery is not nil. @DiP How do you fix the issue?
