I am having the same issue trying to notarize a Electron app with a bundled binary using notarytool. Everything is signed properly, but the notarization status of every submission I've tried over the past two days have just been stuck on In Progress. I even tried submitting something else but this is also stuck on In Progress.
Successfully received submission history.
