I started to use Spline (https://spline.design/) which is super fun, but I have one very frustrating problem, which can make it a waste of time. 
My 3d object(Embed code) on my Webflow site is loading perfectly most of the time, but sometimes it’s just not. And if it doesn’t appear immediately, it’s not appearing after waiting.
If I load the page again, it can appear or not, it’s about luck.
I made the integration based on their website: Integrating with Webflow).
I wrote to the Spline team and they said another user also pointed this issue, and it seems to be a problem with Webflow itself and the way it stores in cache the embedded content.
So there is no way for me to make sure that my 3D will appear every time when someone opens my page? 
I would be overjoyed if you Webflow experts could give me a solution.
