IE11 (internet explorer 11) and Storyline 360 extremely slow

Hi Kristin,

Thanks for reaching out and sharing what you are running into with your published course.

Since you are able to replicate the issue using SCORM Cloud, it'd be best if we could take a look at your project file.

I've opened a support case on your behalf so that you can work 1:1 with a support engineer on this.

Thanks so much for responding! I am uploading the file right now!

Hello - was there a resolution to the above issues please?

I am experiencing a similar problem where my course is running perfectly on Chrome but extremely slow in Internet Explorer and Microsoft Edge. However, my course is only 14 slides and the SCORM is only 7mb so I wouldn't expect it to be this slow! 

Many thanks

No, I'm sorry, not from my end. I never got around to following this issue up completely due to the deadline of the project. The only thing we could "find" was that as soon as you have a somewhat slower internet connection IE will run it slowly... :/

I am experiencing this across the board with my courses. I'd like to know if there is a resolution. I have a feeling it might be connected to the modern player but I'm not sure.

Hi TJ,

Sorry to hear you're also facing slowness in Internet Explorer. We haven't been able to recreate the experience, but won't stop there! A few questions for you:

• What version of Storyline are you using? Click on the Help tab, then About Storyline.
• What Internet Explorer update are you using to view the content? Click the ⚙️ icon, then About Internet Explorer.
•  Is the course hosted on a web server or an LMS?

If you can share an affected .story file for testing, that will help us greatly. You can use this upload link to share it privately. We're eager to find what's causing this!

We too are experiencing this for our courses produced in Storyline (360).  All fine in Chrome, but courses extremely slow in IE and even audio is out of sync in some cases.  Many many of our users are IE.  We publish to html and house our course in a Learnupon LMS.  Any help much appreciated

Hi Joanna!

We're happy to help! Have you tried viewing the course in IE when it's not in the LMS? If not, can you try publishing the course for Web, zipping the published output, and then uploading it into Tempshare? You can take the link and test it in Internet Explorer to see if the courses run faster outside of the LMS.

If this doesn't do the trick, let's bring in our Support Engineers! Please use this link to connect with a member of our Support team.

Hi Lauren

Thanks for getting back to us.  Have published to web and the course runs fine.  However this does  not help us with hundreds of users taking their courses through our LMS, where we need to track and report their progress.

What next?

Hi Joanna!

The next step is to test the course in SCORM cloud which is an industry-standard testing LMS. This helps us narrow down if the issue is specific to the LMS or the course. 

Here's how to troubleshoot your LMS with SCORM cloud.

If the course works properly in SCORM cloud, then I'd recommend checking with your LMS to see if there are any known issues with Internet Explorer and LearnUpon. Some Learning Management Systems will recommend up-to-date browsers like Chrome, Firefox, and Safari.
