Do you have Quiz slides? If so, it depends on your quiz settings. If each question must be answered, navigating beyond the first unanswered question will be disallowed.
Check which option you currently have selected under Quiz > Settings > Required.
If it's NOT set to Optional, try that setting and see if your navigation then works after republishing.
Ah. that makes sense. I'll change quiz setting preferences right now and
let you know.
Thank you Rod. I expect this to solve my problem.
You both gave me the correct answer so...how do you both get points for your recommendation? Thank you for your help.
LOL, give 'em to Rod.
I couldn't care less about points. My goal isn't to accumulate points but to just help out if I can.
Your answer not only solved the question I asked but gave me insight into
another problem I was having in setting up branching. Once I changed the
Quiz setting, my branching from question slides worked! I thank you both
for the tip.
