How to Clear Cache on LG Smart TV [Easy Ways]

Like a quick-reference library, your LG Smart TV uses this cache to store thumbnails, cookies, and other essential elements from your favourite apps.

An outdated cache may also get incompatible with newer app versions, leading to buggy behaviour and crashes as the TV tries to use this data.
