YouTube for iOS and desktop finally supports a feature that was introduced to Android devices back in June 2019 — personalized topics on Home & Up Next.
When the feature was introduced, Android users had the privilege of seeing different topics on their YouTube app. These topics are curated based on their personalized suggestions on Home which depends on what they usually watch on YouTube.
Google also announced its future plans of adding more topics that include types of YouTube Mixes, Creators, Music, Gaming and Learning topics. In the meantime, this feature will also support other languages apart from English such as French, Portuguese and Spanish.
