LMS SCORM export (TinCan) not playing on iPhone

Thank you, very helpful links. It works in SCORM cloud and when I tested on iPhone in Safari I received a "allow pop-up" from this site message. Once I did that everything worked as expected.

But within the LMS I just received the error message as indicated in my first message. I am still confused as to what this has to do with selecting to use the embedded player setting when uploading the SCORM package but I guess I am at (or beyond) my cusp of understanding. Again, it works when I choose the open in new window option.

Thanks again for you help, as always very, very helpful!
