Symptoms
A catalog client script does not seem to work on mobile devices while it does work on the Desktop browser.
Release
All
Environment
Mobile
Cause
This issue is commonly caused by the UI type being set, by default, to "Desktop" so that the catalog client script will only run when viewed from a desktop browser.
Resolution
Make sure that your catalog client script has the UI type set to "All" or "Mobile/Service Portal" to make sure that it is being executed for mobile devices.
