Hi, I’m trying to download the Netflix App for my parents on this IPad . It tells me I need to download IOS13.1

Netflix requires iOS/iPadOS 13.0 or later.

iPad Air, iPad mini2 and mini3 can only be updated to iOS 12.5.

Apple ended major update support for these devices in September 2019. Whilst they have continued to receive “point” security updates, these models cannot be updated to iPadOS 13 (or any later major versions of iPadOS) as the internal hardware does not meet the minimum technical requirements (CPU and RAM) for newer versions of iOS/iPadOS.

Some App developers have dropped support for iOS versions preceding iOS 13.x for technical reasons (often because APIs or software libraries upon which they rely have been updated in the new version of iPadOS, making their App incompatible with earlier versions). 

Whilst many App titles remain compatible with your iPad, if you want or need to access to Apps requiring the most recent versions of iOS, you’ll need to consider replacement of your iPad with a newer or current model that supports iPadOS13/14.

I hope this information provides helpful clarity as to your available options - and the limitations of your existing iPad.

If it is an iPad Mini 1st, 2nd or 3rd generation, it will never get iOS versions beyond the one that's currently running on it, because of hardware incompatibility, sorry.

Regards

Giulio
