Sometimes intended features never make it past the testing phase. Could be that they just caused too many issues with regular game play or they have to make adjustments before they roll them out to everyone. In regular candy crush the bonus wheel was in testing for quite a while before we all got it.
Good idea combo. Above is a a video of 508. After I get the rainbow jenny combo, all the multi hit blockers disappear after one hit from either a fish or a direct hit. Even though they still have all the layers displayed. It does not do that after any other combo.
So did you finish every level of Bubblewitch, Papa Pear, Candy Crush, Solitaire and the many other games that preceded Soda Saga? King develops many games to attract many different types of gamers. Doesn't mean you need to play them all.
The "live chat" is a Facebook feature and has nothing to do with King. I suggest you either turn it off or contact FB to file a complaint. They are pretty good at responding. I stopped using the chat feature due to offensive content.
They probably changed that level after the tips and video you watched were made. It happens to quite a few levels - not a glitch. Hope you pass it soon!
