Clearing the cache on YouTube can be beneficial in several situations. The cache is a temporary storage space that stores data from recently viewed videos to improve the user experience and reduce loading times. However, over time, the cache can become cluttered and cause issues such as slow loading, buffering, or playback errors.
Clearing the cache can resolve these problems and improve the overall performance of the YouTube app. It can also free up storage space on your device, as the cache can accumulate a significant amount of data, especially if you frequently watch videos in high quality.
