Hi @Lola1965 and welcome to our adorable Community 😊 Ye studio is always monitoring the levels and if they are too easy or too hard for players they might tweak it a little bit. If you saw the videos with more moves they were probably recorded as soon as the level was released. Here are some tips from someone who is great at it and the video with 17 moves so you can watch it and find the best approach.
If this doesn't help, I strongly recommend taking a break for a day or two to clear your mind. You would be surprised how many times it helped me to go through the level once I come back to the game.
I would like to use this opportunity to redirect you to a post written by our friend and my fellow Superstar @Elsa where you can read everything you need to know about Candy Crush Saga section in the Community.
