Which yt channel/online app is the best for learning the ukulele for a beginner?

Hi! Im a ukulele beginner, and I just recently started learning ukulele from youscisian and kala. Soon after I finished the basics , it said that I have to pay for premium. So I decided to look for other apps or yt channels which teach the ukulele.

Could you guys please recommend me a channel or an online app which doesn't require premium? And something which is beginner friendly ? Pleaseeeee 😭
