How can I update the Peacock app on my Amazon Firestick?

To update the Peacock app on an Amazon Firestick, one needs to navigate to the main home screen. From there, select 'Apps' and find the Peacock app within your applications list. Highlight the app but do not open it. Instead, press the menu button (the three horizontal lines) on the remote, which brings up an additional menu to the right side of the app icon. This menu offers an option to 'Update' if an update is available. If seen, select 'Update' and wait for the process to complete. If no update option appears, it means that the app is already updated to the latest version available on the Firestick. It's also beneficial to ensure that the Firestick's automatic update feature is enabled for future convenience.
