I ended up using a Node server in the deployment … not sure if that’ll help but figured I give it a shot. Although I’m pretty sure it only works in Chrome.
I think I could make the whole app lighter if I can figure out a relatively quick way which Cesium dependencies I’m not using, too.
Oh, and I’m doing the Salesforce Hackathon today in SF … might have to bring a taste of Cessy with me on this one!! ha Wish me luck!
