Same issue here; Apple changed something. It looks like when you create a new version, the process is being scheduled now, so it may take a few seconds to appear; it never happened before. The problem that we are still facing is that some new versions were either stuck or had data inconsistencies, and we are still unable to create new versions for those apps that have already failed. If you attempt to create a new version with same version as failed, you will get version already exists, if you tried another one, you get an unknown error. Please avoid doing the schedule thing, makes no sense and cause a lot of problem. Please run a query and delete all those version for everyone and revert the last changes. I have contacted Apple already, but we need to deliver urgent fix. We tried to user API and see if the version exists, but it doesn't.
