When importing third-party course content (i.e., AICC, SCORM 1.2, SCORM 2004, or TinCan courses), it is recommended to enable the Use Popup toggle for some courses. Depending in what software and when courses are authored, some settings are deprecated and functionality does not work as expected.
In cases where courses are not working as intended, it is recommended that the Use Popup toggle is set to ON. This generally provides a better experience for Learners, and will allow for some functionality that wont work directly within Absorb to open properly.
Using the toggle otherwise is at the discretion of the Admin importing the course, and can be used if a full-screen mode is preferred over running within Absorb.
