I can’t seem to download Amazon and Netflix apps. They don’t appear in the AppStore.

The Amazon Prime app requires iOS 12 and later now.

The Netflix app needs iPadOS 13 and later now.

If your iPad Mini is still running iOS 11, you need to connect your iPad to a Mac or PC computer, connected to the Internet, and download and install the latest iTunes and let iTunes upgrade your iPad Mini 4 to the latest iPadOS 14.

If a much newer Mac and macOS, the you connect that iPad to the newer Mac and use the macOS Finder to do the iPad uograde to the latest iPadOS 14.

Best of Luck to You!

I have Netflix on my iPad, so I don’t know about your problem. Can you (possibly) send a screenshot? You could also try Netflix online, though it would (hopefully) open it in the App Store for you. And try searching for “Prime Video” instead of Amazon.

Long shot: Do you live in a part of the world where some apps are blocked by government edict?

I just did a search for "netflix for ipad" on an iPad 5Gen running iPadOS 14.2. Netflix and Prime apps showed up as the two top hits.

Hmmm... Maybe try settings age restrictions to off, or to whatever the age need for the apps is. That could possibly fix the problem. To do so, go to App Store > Tap your profile picture > and tap the option where you can set age.

Try a hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

Good Luck!

Did you try quitting the App Store app in the iOS/iPadOS App Switcher by sliding a finger upward on the app window, then try relaunching the App Store app?

Can you send me a screenshot of your software update in the software update page in settings? What I mean is that go to Settings > General > Software Update, and take a screenshot there.

Good news. Thank you for the followup. That helps others.

Glad to hear it! Have a good day and thanks for using Apple support communities.
