Everything we know about Cornerstone on Demand and Storyline!

We are using Articulate Storyline to create courses for our LMS (Cornerstone OnDemand). They typically consist of videos, animations, drag and drop questions, and other Storyline interaction capabilities and end up being around 10 to 25 minutes long. The biggest course we have is 100 MB. For desktop computers and laptops the courses run very well but we are running into a few issues when running the same courses on mobile device. Mobile devices are crucial since these courses are for a transportation company and majority will be taken on mobile devices. We will have over 5,000 people taking this courses soon. Cornerstone does not allow 3rd party applications to be opened through their program so that eliminates the option of using the Articulate app.

Are there any best practices or information that could be provided to us on how to best create and deploy these courses? Are there particular browsers and devices that work best for the courses? We want to maintain that our courses continue to be very interactive and informational.

Thank you!
