Netflix download does not work?

I can't download movies or TV series on netflix.

Whenever I want to download it comes like this: You already have too many downloads, I do not even have one…

What should I do

Manage download devices
Your subscription includes downloads on 2 devices. When you remove a device, the downloads stored on this device will no longer be available.

Depending on the model have only a limited number of devices for downloads or simultaneous streaming.

If you're using the subscription alone and have never downloaded anything, check the activity here to see if they all came from you: https://www.netflix.com/...ountAccess

If not, change the password and make it harder.

Then please the people with whom you share the account to delete some episodes.

It is there why it is not, or what you should do. Did you change the options in accordance with your wishes?
