Tip: For if your custom buttons aren't working
I wanted to share a solution to a problem I had with a recent Storyline 2 course. It used custom navigation buttons, not the buttons provided in the course player. They had been working fine but at some point stopped working correctly.
To be specific, the custom Continue buttons (which used "Jump to slide" triggers) were skipping screens and jumping to the wrong places. Most of them went back to the Main Menu. The triggers, however, were all correct. The problem occurred in the HTML5 version. They were consistent between an iPad and if the HTML5 was viewed in a web browser on a desktop computer.
The solution was to re-create the custom buttons from scratch. Once that was done, they all worked as they were supposed to.
