Hello. I'm encountering an issue with advancing PowerPoint slides automatically. I have a 40-second slideshow with 6 slides. The first slide displays only the title, and the MP3 audio file begins after just 2 seconds. The subsequent 4 slides are set to advance after 9 seconds each, and the final slide should be seen for 3-4 seconds. I've configured these timings in "advance slides," but during playback, the entire 40-second audio plays while remaining on slide 1. Although I can manually advance the slides using the arrow buttons, viewers won't have that option. There are no error messages displayed.
