Rise Closed Captions Not Working

Hello - I am having a similar issue as well with several videos included in a Rise course. The closed captioning icon (cc) does not always display when the videos are viewed within the Rise course that is published to our LMS.  I created the videos in a third party app which does not include closed captioning. Therefore, I added the videos to a Storyline 360 slide, where I created the closed captioning (.vtt file). These Storyline files where then added into the Rise course. The cc icon works as expected when reviewing in Storyline and Rise. However, when I publish the Rise course into our LMS (SCORM 2004) the closed captioning icon randomly appears and disappears when viewing the videos. I did review the WEBVTT file (per Alyssa's instructions above) and see that the settings are correct per her tip (the number does not appear for each caption and there is a period, not a comma, in the time code).  Also, this issue did not exist in previous versions of the Rise course.
