I have a amazon Fire and a 10 user subscription

Avast One Avast One for Android

I cant figure out how to download AVAST Premium Security on this Fire tablet.

First, I’m an Avast user and not an Avast Team member.

I’m not sure if it does support Amazon Fire Tablets.
I googled it - what operating system does fire tablet use:

Amazon Fire tablets run on a custom operating system called Fire OS, which is a fork of Android.

So I don’t know if the Avast for Android available on the App Store would work for the Fire OS or not. Then how to include it in your Avast Premium for Windows license would be the next hurdle.
