Sorry for the experience. We recommend getting in touch with our YouTube Premium Support team who can look into this for you. Here's how: https://goo.gl/SErZLV . Hope this gets resolved.
@TeamYouTube I keep getting the message "downloads remain available as long as your device has internet connection every 29 days" but they do not stay. If my account logs out I loose ALL downloads. connected to wifi or not. I have a Lenovo yoga tablet
