Ummm where do I start

So I like this app but here are some things I dont like 1. Why dont they have normal music like shake it off 2. How u cant subscribe to youtubers 3. There are barely any videos 4. (Finale) they only have music from kids bop they dont even have heathens!!!! Other than that its kinda ok ? from Puppys and kittens

crazy cats and dogs about YouTube Kids, v2.22.7
