Hi @bright-pharmacist-73946, could you please provide additional information about this issue? We've conducted multiple tests, and each time we received features whether background sync was set to true or false. Additionally, in this version, we have fixed the issue with the tracking callback, which now runs only once per experiment.

Hi @calm-dog-24239 thank you for getting back to me. here is the setup I am using in the Swift SDK.

let growthBookSDK = GrowthBookBuilder(apiHost: "<https://cdn.growthbook.io>", clientKey: <client key defined in the connection>,
encryptionKey: <key defined in connection>,
attributes: <client attributes>,
trackingCallback: trackingCallback,
refreshHandler: refreshHandler,
backgroundSync: false).initializer()

After the refresh handler is called, I check the features I have defined ( I have two defined for the environment I am testing in) and the result I get back is :

po growthBookSDK?.getFeatures()
▿ Optional<Dictionary<String, Feature>>
  - some : 0 elements

Yesterday when I posted I could change

backgroundSync

to

true

and get features back. Today, no features are returned regardless of `backgroundSync`state. I am not really sure what is happening at this point. I do notice that on the connection setup screen in the GrowthBook App, the Swift SDK Version says 1.0.44.

Thank you for the information. Now it will be easier to detect the issue. We will take a look at it and let you know when we will fix it.
