Hi, @bright-pharmacist-73946, we also checked these two versions with the team, and we found features in 1.0.44 and in 1.0.46. However, we also identified one thing that could explain why this occurred. In the new version of the iOS GrowthBook SDK, we changed its initializer. Please pay attention to the new way to initialize the SDK. Now you have to add the API key and client key separately, without including “api/features” or “/sub/“. Just input your API host, for example: “https://cdn.growthbook.io”, and your client key, which should resemble this format: “sdk-YUtMizl6frtpEyL”.
