Continue button disappearing in completed Rise courses

We're experiencing this same problem. Our client at The Coca-Cola Company tasked us with building a Rise course with auto-playing narrations. Since there isn't a good solution for that in Rise (even though many people are asking for it), we discovered that including the audio in Storyline blocks allows narrations to auto-play. We added "Continue" buttons after each Storyline block to ensure they would play one at a time. Unfortunately, now that the entire course has been built, we've discovered that if a user completes a lesson and then goes back to it to review, all of the blocks play at the same time. We really need a solution for this!
