Yes, Netflix has a limit of 100 titles on a single device. Once your limit has been reached, you will see an error message that prevents any additional downloads. Since Netflix has an expiration date attached to the download, you can watch new shows as soon as your other downloads expire or you delete them. Any content removed from the platform automatically expires. You will get a notification seven days ahead of any pending dates. While some titles may remain available for viewing for weeks, licensing restrictions may mean some titles expire within 48 hours of the download. There is no way to know this information ahead of time, and it still counts towards your total of downloads.
