Can't find the Amazon video app on Xbox 360 or Windows 10 app store

Hey GAUV,

I'll post the link again this way:

"To watch Amazon Instant Video content on your console, you need:

• To be signed into an Xbox Live
• At least 75 megabytes (MB) of available storage space"

"Install the Amazon Instant Video app

1. From Xbox Home, go to Apps, and then select Browse Apps.
   
2. Browse or search for Amazon.
3. Select Amazon to download the app. Once downloaded, the Amazon Instant Video app automatically starts.
   

To start Amazon Instant Video later, go to Video, My Video Apps, and then select
Amazon."

If you still can't see the app then I would recommend to
clear the console system cache.

It appears that Amazon does have an app for the Xbox 360 according to the FAQs regarding this question.

Hi There,

Yes, there is an Amazon Prime Video app for Xbox 360. Are you able to find it in the marketplace?

No, there isn't an Amazon music app for the Xbox One. You should contact Amazon, see if they have any plans to release one. The only app available from the Microsoft store is for Windows 10.

Hi,

To get the Xbox Accessories app on Windows 10, go to the Windows Store and search for Xbox Accessories.

The Xbox Accessories app is not available on previous versions of Windows.

If you can't find the app on Windows Store, you can clear and reset Windows Store cache then search for the app again.

To do this, follow the steps below:

1. Press Windows key+ R on your keyboard.

2. Type wsreset, and then hit Enter.

Let us know how it goes.
