Closed captions not working

I've encountered a CC issue as well. It seems like a slight variation on the theme. In my case, the captions do appear, but the first block of captions (as seen in the captions editor) will be missing. So far, it affects 4 of 10 slides I've checked in a 95-slide project. 

Someone in another thread (from 4 years ago) had a similar problem and said bumping the audio start point a 1/4 second down the timeline resolved the issue. In my case, that would create a lot of timing issues, since I have text flying in to accompany the speakers and V/O. 

I'm going to try inserting a dummy first element with either no content at all, if that's possible, or a space, or, if that fails, an ellipsis. Wish me luck. I'll report back. 

I'll note that I'm running the latest version of Storyline 360 (patched it yesterday), and that the error is visible both in preview and in Review 360. 

Splitting the initial CC block into two and adding "..." (blanks weren't possible) as the content of the first caption block fixed the problem. The "..." caption doesn't appear, but all those following it do. It worked in Preview. I haven't published to Review 360 yet, but I suspect it'll work there, too. 

I submitted this issue as a support ticket. It's still being reviewed, but the person I worked with via chat found another workaround, which is to remove slide transitions on the affected slides. This does work and it is quicker to apply than my fix. Also, in my particular project, there was no downside to removing the slide transitions. The elements themselves have their own transitions (just fades), so you don't notice the lack of fade on the slide itself.
