Hi Brian,
I specifically timestamp each request I make to the controller to avoid caching issues however Chrome has been caching some requests according to some users. I will re-examine this however I doubt I can do more than what I already am to prevent caching.
I opened the URL you provided and I got no error. Furthermore, when I load the app using the browser method, I don’t see the error in the console. If you open that URL yourself, do you see the icon or instead get an error?
Thanks!
Update: I am able to replicate this issue on some networks/devices and therefore am hunting down the issue. It appears to lie with CloudFlare, our CDN, since the server is never even seeing the request for those files much less giving out a 403 error.
