Netflix download problem?

The problem with netflix is that when I download something, the message comes from time to time: a Wi-Fi connection is required to continue this download. You know what I can do there (ps: even believe that it will come when my phone screen goes out).

Turn off the automatic lock in the settings.

Otherwise, the WLAN connection may be lost again and again.

If it still doesn't work, apply https://help.netflix.com/...lix.com/de, they can help.

Do you mean that I block: only WLAN, should turn off?
