Your app page should show you which upload permissions you have been granted.
If it says the request is pending, it means it has not been approved by Vimeo staff yet. If it says "owner" it means the app owner can upload to their own account. If it says "PRO", "Plus" or "Basic" it means that users with those subscription levels are able to upload to their own account using your app.
If you think you should be able to upload, and can not, contact Vimeo at vimeo.com/help/contact
