Embedded Shapediver Viewer Inconsistently Showing User Inputs

I am currently working with a web developer for the final version of grasshopper+shapediver project. I was wondering if anyone on the shapediver team could help us debug an issue. We have separated the inputs as individual slides with a range slider controlling the input, and the final shapediver visualization is shown on the last slide. See example here (note: currently only works on desktop devices and doesn’t work on safari):


About 15-25% of the time, the final visualization shows the “default” shapediver input values and doesn’t reflect the user inputs from the sliders. It seems to be an issue with the iframe loading properly, because when I check the final code, it always reflects the updated user inputs.

Any help would be much appreciated!
