Netflix download not working?

Since we're going on vacation tomorrow and most likely won't have Wi-Fi there, I wanted to download a few Attack on Titan episodes. But now it says that something has been downloaded on too many devices. My father then deleted a few downloaded episodes from his series on his cell phone, but that's still there…

Maybe knows why and can help me?

Yes, that's because multiple devices are not only downloading you and your father or you got the cheapest subscription and only two can download

You have to regulate this in the Netflix account, because you can delete all downloads that have been made with this account on all devices without doing it manually on the devices
