Everything we know about Cornerstone on Demand and Storyline!
I thought I would start a thread about Cornerstone on Demand so there's a central place for people to read and add to. There seems to be a dearth of information about how CSOD and Storyline interac...
What is the word regarding the Google Chrome Update 80 coming out Feb 4, 2020 and course size limitations? Could any offer any insight on the information below as to why Google Chrome is doing this and steps to take to "reduce message size" or keep "message size" under their new limit - Not sure exactly where or how to do this. Does this have anything to do with the way a course is built in Articulate? Or how the final data is sent from the course to Cornerstone? Or what? Cornerstone is clear to say this is not their doing it is Google Chrome - but it effects all cornerstone courses. (Or will it stop there?) How would I limit said message size? Any help or feed back would be graciously received. Thanks!
"Google will release Chrome version 80 on February 4, 2020. With this release, Google is making significant changes to Chrome’s Window Close behavior that will impact how online courses communicate a user’s exit and completion status to a learning platform. NOTE: There is no impact to other supported browsers, i.e. Firefox, Safari etc......We sent this announcement ......
.....In addition to the Chrome Window Close behavior, Google is making another change that will affect specific courses for you, directly.
The impact on you
Chrome version 80 will now limit the size of status and completion updates that your course can send upon Window Close. The new limit per message is 64KB. If the limit is exceeded, course status and completion will not be sent to Cornerstone and these statuses may not be accurate.
What we're doing to help
We have audited all SCORM courses and have identified the below courses within your portal that exceed the new message size limit. These courses will need to be updated to correctly track user's status and completion.
Recommended next steps
If these courses were authored within your organization, you should update them to reduce the size of the message sent to Cornerstone upon Window Close.
If these courses are purchased from a third-party, you should work directly with the provider to ensure the new limit is met.
We encourage delaying your organization's update to Chrome version 80 until you have confirmed that your content is compliant. Other web browsers are not impacted by this change.

Thank you for your attention to this matter.

Hi, Laura.
This Chrome change limits the size of the communication between an LMS and a course--not the size of the course itself.
The good news is that the most resource-intensive communication between an LMS and a course is suspend_data, which is already capped at a maximum of 64 KB by even the most generous LMS standards. We've never seen a course that approaches this level of runtime data, so we anticipate no impact as a result of this Chrome change.
Please let us know if you need anything else!
