I would like this conversation to play: First person speaks on slide entry (THIS WORKS), and the second person should speak right after (THIS DOES NOT WORK PROPERLY).

ISSUE: the second person: the timeline is set up so that the audio plays at the end of the previous audio. However, it stops, and I use the PLAY button to make it start; on the first slide, it starts about 4 seconds later; on the other slides, it starts 10+ seconds later. Every other interaction works perfectly….Can anyone help me fix this playtime?
