Try this. I’ve made it a lot easier with this updated version of the setup. It doesn’t involve having to copy and paste from the clipboard anymore, but you have to follow these directions pretty much to a T. The magic happens in the “Text Articles” iCloud folder, so it won’t work without it.
It’s been a bit since I’ve used this so let me know if there are any issues, but it should still work if you follow the steps to set it up above.
