You're welcome, tmudavid!
When you export a Rise course as a standard SCORM package, the published Storyline Block is included in that package. Although the Block is initially added to Rise from Review, the exported course doesn’t reference or load the Storyline content from the original Review link.
The Storyline Block will continue to work normally in the LMS without a connection to Review. If the author’s Articulate 360 subscription ends or the source Review item is later deleted, it won’t affect an already exported and deployed standard SCORM package.
Please keep in mind that the original .story project file isn’t included in the SCORM output. If you ever need to update the course, you must edit that source file. Then publish the updated version to Review, update the Storyline Block in Rise, and export a new SCORM package.
This behavior differs from a Connected Package, which hosts the Rise course through Articulate servers and relies on that hosted course remaining available.
