i'm trying to download netflix on my ipad, but it needs iOS 11, however, my ipad says it's up to date on software?

You are using a 7-year old iPad.

You want Netflix on iPad, you will need to purchase a new or discounted, refurbished iPad from Apple that will handle all of tne newest iOS versions and can use the most up to date apps.

Sorry, but Best of Luck to You!

If its saying 10.3.4 is up to date, you have an iPad 4 and it cannot be updated beyond 10.3.4.

I can’t seem to open Netflix

This is a refurbished Apple iPad

Why not? what happens when you try?

What model of iPad exactly? Settings->General->About->Model
