RISE and Litmos - upload failing

Honestly, it is irrelevant whether it works in Scorm Cloud or not. My company uses and pays for a different LMS. The issue is that 360 works for everyone every time on our LMS in IE and Rise does not. It works for ~ half of the people I am assigning it to as a test. My LMS tech support people are not able to see an issue (of course) and I get to re-do all of the course I built in Rise in 360. I guess my disappointment comes from Rise not working the same way 360 does. Honestly, Rise seems like a good idea but it simply doesn't work. I am seeing a ton of posts on various forums with the same complaints and the response is always 1) Try it on Scorm Cloud and 2) Contact your LMS. Neither of which address the core issue that Rise is not functioning the way it is supposed to. 

Sorry if this sounds like a frustrated rant, but I am looking at a bunch of extra work because I trusted that this program would work as well as 360 and frankly, I paid for a product that I cannot use.
