note same code with 1.0.0-beta.8 is working fine

[DavidWynnII]

I'm experience the same issue on 1.0.0-beta.17. Works for window desktop but not android.

** i'm using Maui Blazor .net Core 8 with a Razor Class Library

Having the same issue. Same exact code, calling the same deployed model: Blazor in MAUI on Android throws the above exception, Blazor in asp.net works fine. Last know good version is 1.0.0-beta.15.

await foreach (StreamingChatCompletionsUpdate chatUpdate in client.GetChatCompletionsStreaming(chatCompletionsOptions)) {
    if (chatUpdate.Role.HasValue) {
        conversation += "Assistant: ";
    }
    if (!string.IsNullOrEmpty(chatUpdate.ContentUpdate)) {
        answer += chatUpdate.ContentUpdate;
        conversation += chatUpdate.ContentUpdate;
    }
    StateHasChanged();
}

Version 2.0.0-beta.1 also does not work (Android); when attempting to call CompleteChat(messages), it returns "Operation is not supported on this platform." (it works on Windows.)

Facing the same issue here, working in Windows, broken in Android. And I cannot go back to 1.0.0-beta.15 because it does not support me sending binary data to the sdk.
