Hi, I found the same issue by accident and it means our music playing service is no longer working. I can confirm that the loadeddata event no longer fires on iphone. But it DOES work on Ipad, same code, same IOS 17.4. This is very concerning because we have had a lot of playback issue on IOS due to the requirement of user interaction to start a play (caused a lot of headaches) and now using the buffer preload and play method stops working silently for iphone only. Apple, can you please investigate this and resolve?
