Disable Next button first visit, enable for second and any other visits
I've disabled the Next button on many slides that contain (1) animation or video (until the timeline ends) and (2) multiple layers/tabs (until the state of the tabs is visited). The disabled function works perfectly the first visit, but it is permanently disabled on any additional visits. My goal is to permanently "unlock" the Next button on a particular slide after the user's first visit to the slide.
I've read in previous discussion questions on the topic that for slides with tabs that I want to ensure are visited, I can use variables instead of states to fix the Next button issue. Any experience or thoughts with this?
Also - any suggestions on how to make the Next button work on 2nd visits when the Next button is disabled until the end of the timeline on the first visit?
Many thanks for your time and expertise!
