Hi Mayanme2,
As kip stated, it can take between 24-72 hours for the On Demand content to be updated. We do rely on the network providing us the content to upload to our system. Occasionally, when we receive the content it is corrupt or wrong, which means we have to reach out to the network again. If you provide us with specific details of what shows have not been updated, I would be happy to look into it.
