Storyline course published in LMS shows incomplete content in a slide.
We had published a training for our client's LMS and it was working fine for many months but now we receive errors, which looked quite illogical. Some of the slides did not show some content so the user could not proceed and complete the course. It happened only for few users while for others it worked fine. It does not look like a browser or Internet issues as the user has tried it on different browsers and devices. Also the slide looked like completely loaded as the content missing was the middle section of the slide. I am not able to re-generate the bug but the client has sent the screenshot of the error. Has anyone faced this issue before? What could be the possible reason for this?
The screenshot is attached to this message. The missing content is a third rectangle between the two rectangles after the text. Any help is highly appreciated.
