I've developed a course in Rise 360 and uploaded two interactions which I created in Storyline 360. one of the activities is a tabs interaction with 8 tabs. The problem is that one or two of the tabs randomly disappear in the activity and the user would have to move back in the course to get it to appear again. I've checked all my triggers which are correct and locked down contents on all slided. Has anyone else experienced this? Can anybody help? I'm on a tight deadline.
