App download

Your iPad is too old, now, for any more iOS upgrades/updates.

Sorry.

An iPad 2nd generation is a 10-year old iPad, now.

Netflix versions go all the way back to iOS devices running iOS 5.1.1

There is one last thing you can try/attempt, if you need an older version of an app, like Netflix.

If you own much newer iOS device that can run either iOS 12 and.or iOS/iPadOS 13 and later, you can install the most recent app/s onto that more recent iOS device.

Then go back to your older iPad, open the iOS App Store, go to the Purchases section of the store app, search for the app/s you wish to try and download to that older iPad and see if an older version of the app is allowed to be downloaded/installed to that older iPad.

These newer iOS/iPadOS devices must use your same Apple ID user account and password as the older device you ard trying to get an older app for.

Failing that OR IF NO joy, then there is nothing more to be done.

It's 2021 now!

If you need/want an iPad with an up to date iPadOS with access to current, updated apps, then you really need to seriously consider a new iPad model OR a much, MUCH “newer” and less expensive, refurbished or used iPad models, from better known, trusted Apple product/device retailers/resellers, locally or on tge Web/Internet, capable of running the latest iPadOS versions.

There are PLENTY of newer, older iPad models that can run the latest, current versions of iPadOS.

Sorry & Best of Luck to You!

You will need a newer iPad to download Netflix. Your iPad 2 cannot be upgraded beyond what it has now (or not by enough).
