Continue Block set with "Complete the Content Above Before Moving On" not working

Hi Christopher, 

thanks for sharing your solution. :)

In the meantime a colleague of mine found another solution as a linear progression of layers doesn't work in my case.

We have forced a solution by creating an animation loop which acts as a trigger to continuously check whether our newly created ("layer-visited" true/false) variables are true. These variables are set to true once the timelines start on the respective layers. This way, my base slide continuously checks the variables for layer-completion and, once they are all true, the course is set to completed.
