Why the buttons blocks themselves?

It sounds like the issue you are experiencing with your Xamarin app is related to the handling of button click events and the asynchronous nature of UI updates. When buttons are pressed rapidly, they may trigger multiple click events, which can lead to unexpected behavior such as the app becoming unresponsive.

To address this issue, consider implementing the following strategies:

1. Disable Buttons Temporarily: You can disable the buttons immediately after a click event is triggered and re-enable them after the operation is complete. This prevents multiple clicks from being processed simultaneously.

      private async void Button_Click(object sender, EventArgs e)
      {
          var button = sender as Button;
          button.IsEnabled = false; // Disable the button
          try
          {
              // Perform your operation here
              await Task.Delay(2000); // Simulate a long-running task
          }
          finally
          {
              button.IsEnabled = true; // Re-enable the button
          }
      }
   

2. Use Command Pattern: If you are using MVVM, consider using commands with CanExecute property to control the button's enabled state based on the execution of the command.
3. Throttle Click Events: Implement a mechanism to throttle the button clicks, allowing only one click to be processed within a certain time frame.

By applying these techniques, you can help ensure that your app remains responsive even when buttons are pressed quickly.
