If you chose the Translation+Editing service, the translation project is in review until the editing project has been completed. This is why you cannot see the translation.
When a project is “In Review” it means that the translation has been completed and it is undergoing an additional quality check. During the review process one or more independent reviewers go over the translation to ensure the quality of the translation.
When the the quality check and/or the editing have been finalized, you will see the “Ready” status in the project page. At this stage you'll be able to download the final translation from the project page.

I’ve received my translation, so why isn’t my project marked as ‘Completed’ on my projects list?
