Sharing GarageBand with iOS

There is a specific menu item in GarageBand, to share your PROJECT with your iOS device. It does not work, period, and even with some unnecessary workarounds, it collapses all the tracks into one track. I could just export it all mixed down to one track if that’s what your menu item does (and doesn’t even do that!). A GarageBand multi-track recording should be accessible by any Apple device using Apple Silicon and the latest iOS or macOS. Not mixed down to one track, c’mon, Apple, you know this.
