If the next module has not been unlocked after three days, please check if the module you
worked on before was registered as completed in the program. A completed module is
marked with a white check mark in the upper left corner of the module image (see picture).
If
the module is marked with a lock instead of a check mark, you have not completed it yet.
Open the module again and click on "continue" to go through the final steps and complete
the module.
