Rise loading state and loading time

We're experiencing issues with the loading times of Rise courses. 
Our Rise courses are embedded in our LMS (Moodle) using SCORM. Technically this is working fine, but the loading speed of our Rise courses and/or de loading state presentation is a little bit of a UX issue. 

When starting a SCORM based e-learning in our LMS, it first loads a SCORM viewer, which than loads de SCORM file and presents this to the user. We know this sometimes takes a little while and an bad internet connection can cause this to be slow. In the LMS a notification/loading state is offered to inform users, this might take some time. 
But after the SCORM viewer is loaded it's up to the SCORM file to take over this function and either display the e-learning or display a loading state.  

While a Rise SCORM file does offer a loading state, it can take up to 10 seconds for this message to appear after the SCORM viewer has loaded. Resulting in users thinking they have a problem or there is a problem with the e-learning/LMS (see the attached animated GIF for an example). 
The size of a course has little effect on the time e.g. a Rise course consisting of 3 simple blocks text, question and text will also take muiltiple seconds to load. And we don't have this issue with the SCORM files generated in Storyline. 

Does anyone recognise this issue and/or has anyone tips on how we could improve the loading time of make sure the loading state is offered/shown sooner? 

Kind regards,
