The changes will begin to reflect primarily in the web version of YouTube and in the Android and iOS app, after which you'll reach the rest of the platforms.
The most noticeable change we see in this new format is the larger size of the home screen thumbnails and the ability to display longer titles. In contrast, fewer videos will appear on the home screen. If this design is familiar to you, it is because in August the company decided to conduct some tests.
Among other developments, the possibility of adding videos to the playlist is offered simply by keeping the cursor on the thumbnail of the video in question, and clicking the corresponding button. It should be borne in mind, of course, that if YouTube is closed, the playlist will be deleted, and to save it will be necessary to continue to use the function "See later". In this sense, the thumbnail also provides the option to stop watching video suggestions from specific creators.
Finally, YouTube announces the functionality of the desktop version of YouTube, which has already been on Android for some time - the possibility of following specific topics that interest us, so that videos and creators associated with these topics appear in our recommendations.
