Today, Netflix announced that Premium members can now download content on more devices and use spatial audio for over 700 titles. Both upgraded features are available at no extra cost.

Premium subscribers are able to download Netflix titles to watch offline on six devices at a time. Previously, the plan would only allow downloads on four supported devices at once. For large families looking to travel this year, this upgraded feature will probably be very convenient.
