Pause Media trigger not working in Storyline 360

Hello, I am trying to create an interaction where the learner clicks a button that takes them to a layer that plays a video automatically in the slide. I've added a trigger to pause the video at a cue point and then re-play it when they click the back button. There is also a trigger to hide the layer when the video completes playing.

However, once I add the pause media trigger, the video does not play. I've also tried adding a trigger to play the media when the timeline starts, but the pause media trigger seems to be preventing the video from playing.

I am following this tutorial so I know that it should work.

I've attached my file - any idea what I might be missing?
