I just wanted to ask what happens if I download episodes to watch offline and then while I never connect to the Internet my Netflix subscription expires, are they blocked anyway or can I watch them until I next turn on the Internet?
Access to it is not possible without a valid subscription. The app also remembers how long your subscription should be valid. It is therefore not possible to use it simply by staying offline.
In fact, downloads can't be random. As a rule, they expire after 30 days at the latest and must then be confirmed again via a short online check, even if the subscription is still valid.
So, in my experience, you have already downloaded the films / series and are also on your smartphone, so you can watch them for a certain period of time. Because if you open a episode, you have 48 hours to watch it. Yes, so the answer from the other can't be correct.
