This has to do with the limitations of Avid, where Avid blocks the UI of the app including our Panel while it's doing an export operation. It will mostly show up when users are doing big batch operations. We don't want to "starve" other operations like uploading and encoding, so we try to run through queued operations in the order the user did them, but that means sometimes non-export operations have to wait for an export to complete, and export operations have to wait for non-export operations to complete.
