The Utter Failure of Some Candy Crush Events: Can't Play the All Stars Event, WON'T play Milestone

Hi folks! I’m Suzy, the Gaming Guru--offering help with Best Fiends, Candy Crush, and other games. I’m working on making audio talkthroughs of levels that feature tips, hints, tricks, and strategies.
UPDATE: I played the impossible milestone level on a different browser, and it seemed easy...probably because I'd lost so many times when it was impossible that I knew what needed to be done! https://youtu.be/nzvGJav-1fU
