Hi John,
Did you get a chance to check if the 'Hide Cover Page' works on a course in SCORM Cloud? If it works in SCORM Cloud, then the issue could be LMS-related, and it would be a good idea to reach out to your LMS admin for assistance.
If you're also seeing the issue in SCORM Cloud, please open a support case here, and we'll work with you closely to fix the issue.
As for your suggestion on using the setting 'Cover Page' , we really appreciate you letting us know that setting could be confusing. I shared your feedback with my team and we'll update you once we have information to share!
