Hi @djones, I think you are referring to this topic, but please correct me if I'm wrong:
That issue was fixed with Cloud release version 3.40.0. If you are running into the same problem, it may be relate to a new bug. Creating a new topic is definitely what we want, thank you for doing so.
Could you attach screenshots with the configuration of your upload? We would love to see if you have an event handler attached to the component, or you are using its built in functionality only.
