Rise courses not rendering correctly in IOS

Hi

I am seeing an issue where Rise courses are not correctly rendering on IOS mobile devices. I have tested this on ipads and iphones on IOS 13.7 to 14.3 BETA. The issues cause, random text to be missing, images and other interactions not to render at all and font sizes are all over the place. I have tested the same content on android and it works perfectly. 

This issue occurs if i view the course via the share link or if I load it as a SCORM to an LMS. When viewed in the preview window everything renders as expected. 

Needless to say this is a huge bug if it effects all IOS devices. Is this a known error and when can we expect a fix?

Thanks

Mike
