Globo Mega Menu, Navigation

After publishing the Menu for the first time it worked fine. When we made some changes and tried to publish it again the Menu didnt change at all. It says you need to wait a couple minutes, but after 3 times of waiting at least 2 hours we are done with this application. Support did respond to our problem but didnt do anything about it. Only 2 stars because it is kinda easy to use.
