To do that, on your Fire TV Stick’s remote, press and hold down the Home button. In the menu that opens, choose “Apps.” If the remote isn’t working, there are ways to fix it.
On the “Your Apps & Games” page, highlight (but don’t open) the app you want to update. Then, on your remote, press the Menu button (three horizontal lines).
You’ll see a menu to the right of your screen. Here, select “More Info.”
Your app’s Appstore page will launch. Here, select “Update” to begin updating the app. If you don’t see this option, and you only see “Open,” your app version is already up to date.
When the Fire TV Stick finishes installing the update, you’ll have the most recent version of the app. And you’re all set.
That will get you the most recent version of your chosen app on your Fire TV Stick.
Bonus Tip: Enable Automatic Updates for Fire TV Stick’s Official Apps
If you’d like to activate that option, then first, choose “Settings” (a gear icon) from your Fire TV Stick’s home screen.
In settings, select “Applications.”
Choose “Appstore.”
Select “Automatic Updates.”
Beneath “Automatic Updates,” you now see “On,” which indicates that the feature has been enabled.
And that’s it. From now on, your Fire TV Stick will automatically check for and install the available updates for all your official apps. Enjoy!
