Hi Michael!
Sorry to hear you've run into this setback!
A helpful way to troubleshoot LMS-related issues is by testing your SCORM content in an LMS test environment like SCORM Cloud. If the full-screen option functions as expected, it's possible this behavior could be related to the LMS that's being used.
However, if you're still unable to expand to full-screen when testing with SCORM Cloud, please share the affected .story file here in the discussion or privately through a support case.
Thanks, I did try SCORM Cloud and it works as expected so will look into issues with the LMS we are using.
