@LalithaNadimpalli this could be a good one for you to pick up next. Maybe see if you can reproduce in a new UWP project first? At least we can see if it's a general issue or specific to WinUI 3?

@Dieveral what Windows App SDK version are you using in your app? (@Arlodotexe we probably want to add that to our issue form template too. (For both WinUI and WindowsAppSDK - do they support conditional questions based on other answers yet?))

I am reproducing the app in UWP using TokenizingTextBox code(XAML and .cs) but I see the issue user pointing to when I run the simple sample app provided

[michael-hawker]

Thanks @LalithaNadimpalli, want to attach your reproduction project here as well?

I built this version of the control, so let me know if you have any questions in digging into what might be happening here when the text isn't being set.
