Batien writes that he’s released Org 9.3.1. It’s a bug fix so you should probably update if you’re having any problems with Org 9.3. I updated yesterday and haven’t had any problems. Of course, that’s a study of \(n=1\) so you may see different results.
Thanks to Bastien, Nicolas, and all the others for the hard work they do to bring us this essential package and for keeping the development robust and active.
