Hi Debbie,
Can you check this SCORM 1.2 package with your LMS?
SCORM1_2_Check_Resuming.zip (222.3 KB)
You can open the SCORM content, go to slide 2, close the browser tab then open it again to see if it can resume from slide 2.
Each time you open the SCORM content, please also press F12 to open the browser Developer tool, copy and send us the entire log in the Console tab before closing the browser tab.
Regards
