GrowthBook Users

It seems this SDK does not work correctly. I think its because in `decryptPayload`
```data.features = JSON.parse(
        await decrypt(data.encryptedFeatures, decryptionKey, subtle)
      );```
Is async,

How are you evaluating the flag? It's likely you are evaluating it before the decryption happens. <https://docs.growthbook.io/lib/script-tag#using-feature-flags|https://docs.growthbook.io/lib/script-tag#using-feature-flags>

The example above shows how to listen for the `growthbookdata` event, which will fire every time the feature definitions or attributes change

I’ve used snippet visible in SDK
```&lt;html&gt;
&lt;head&gt;
    &lt;script
            data-api-host="<http://localhost:3300>"
            data-client-key="sdk-9m8LOKhsUcWrizJQ"
            data-decryption-key="u+xDcOpJfNYiBMFdHkgdSw=="
            src="<https://cdn.jsdelivr.net/npm/@growthbook/growthbook/dist/bundles/auto.js>"
    &gt;&lt;/script&gt;
    &lt;script&gt;
        const r = window._growthbook.getFeatureValue("simple", false);
        console.log("!",r,"!")
    &lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;&lt;/body&gt;
&lt;/html&gt;```
With debugger I can see it tries to decrypt twice. First w/o key, then flag is evaluated (console.log) and then with a decryption key (but lag is not reevaluated)

It works for other SDK tho

Yes, you must wait until the SDK is ready before you evaluate a feature flag using the methods in the docs. The code you have now is subject to race conditions and will only work some of the time in ideal circumstances.
