Storyline 360 issue with synchronous xhr requests in page dismissal in Chrome

Sep 09, 2021

I recently started building some SCORM courses in Storyline 360 to import into our ThoughtIndustries LMS. We built some a few years ago and didn't encounter any issues. Now, I can't seem to get the SCORM data back to the LMS when using the Chrome browser. My research has led me to think it is related to Chrome no longer allowing synchronous xhr requests in page dismissal (onunload or onbeforeunload). Which I believe is the way Storyline communicates the SCORM progress from page to page.

Is anyone aware of a workaround that doesn't require a change in the Chrome browser settings? Perhaps javascript triggers when the page/slide starts instead.
