Chrome 83 completion issues on Totara/Moodle with SCORM

Hi all,

We've had a number of issues recently with SCORM pacakges not marking as complete when completed on our Totara LMS. (Totara is based on Moodle, and this issue seems common amongst others who use Moodle).

For reference, we are using Captivate 2019 11.5.0.476

I posted on the Moodle forum and I was alerted to this support page which outlines the causes for issues with Chrome 80 and Chrome 83: https://apps.support.sap.com/sap/support/knowledge/public/en/2876002

It seems the key issue relates to Chrome blocking Synchronous API requests.

All of our SCORM packages report data to the LMS on the page being exited, but it seems like this is no longer supported by Chrome. Our only solution so far has been to switch on the setting to send data on every slide, but we are concerned about the effect on performance/pressure on the server. It also will require a lot of production work as we manage hundreds of SCORM packages.

I know that Adobe have previously released a Hotfix for the related (?) issue with Chrome 80 but only for xAPI.

Does anyone know if there will be a hotflix for SCORM 1.2 and SCORM 2004? Is anybody aware of any workarounds? Is anybody else experiencing this?

Thank you for your help in advance! Happy to provide further details if needed.

Mike
