Adding my experience here as well. I started getting the same 7000 error code randomly two days ago during notarization. It seems to be triggered with larger builds. I tested out notarizing a small 8kb file, and that took 25 minutes, which is much slower than expected but eventually succeeded. My actual applications are around 500mb, and those either hang forever, or result in the 7000 "Team is not yet configured for notarization" error. I'm blocked on publishing any new app updates.
