@AnnaErrington Your query is related to CCS and needs to be posted in a different community. Here only issues related to Friends Saga game will be addressed.
Hey there @AnnaErrington, thanks for your post! As @Veeresh mentioned, this is the Candy Crush Friends Community therefore I am moving your thread to the Candy Crush Support where I'm sure someone will be able to help you out
No one has been reporting this as a glitch so I don't foresee the studio making a change on this in the near future. A lot of these higher levels require boosters and that is how the majority of players are clearing them now. But in the video he didn't use any boosters.
