Guys, I just figured out a temporary solution for IOS 13 users trying to export with sound. Use the screen recorder, go a few seconds before the end, hit record, then hit play and go into full screen. After recording the animation, trim the edges where you were hitting record, and stop recording, and boom, now you have an animation with sound in however many seconds long the animation is, with high quality. I do this for all of my animations because it is better quality, and quicker.
