How do I advance to next level in Candy Crush when it says I've completed all 3 stars?

I've completed all stars in level 80, and it says Wonderful! Level completed! but it doesn't advance to level 81.  What can I do about this?

Theres a roadblock after this level so you need to click on the little aeroplane and then either ask your Facebook or Kingdom friends for help or use some gold bars to proceed to the next level. The little menu pop up will give you some options.
