Cloud Storage - No 'Access-Control-Allow-Origin' header is present on the requested resource for AngularJS view

Question

According to Chrome dev tools, my requests to get my html partials have the origin header https://site-name-here.com and request header GET.
I have the following JSON file set to my bucket:

[
    {
      "origin": ["https://site-name-here.com"],
      "responseHeader": ["content-type"],
      "method": ["GET"],
      "maxAgeSeconds": 3600
    }
]

However, whenever angular tries to get the view, I get the following error: XMLHttpRequest cannot load https://storage.googleapis.com/bucket-name/view-path.html?. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://site-name-here.com' is therefore not allowed access.

I am also serving javascript and css files from Cloud Storage, but they're working fine, I assume because CSS doesn't have CORS restrictions and I'm using $sceDelegateProvider.resourceUrlWhitelist() in Angular for the scripts?

Edit: Working now, I'm assuming something was cached and it was serving me an old version.

Just to support @Idcmp's answer, the CORS policy does take a while before taking full effect (this is not documented tho). I've spent ~2 hours trying to figure out why I'm still getting CORS error in browser even though I use the below policy (which is highly NOT recommended, but it's fine for my personal testing project).

{
    "cors": [
      {
        "origin": [
          "*"
        ],
        "method": [
          "*"
        ],
        "responseHeader": [
          "*"
        ],
        "maxAgeSeconds": 3600
      }
    ]
}  

ps Take a coffee break after applying a new CORS policy, you definitely deserve it
