Probably I do something very simple wrong but I try to follow the single instance per app example and if I debug my code I can see the cascading variable getting the instance.
I can send the following code without any error in the code or in the console of my browser
Text = "TEST",
ThemeColor = ThemeConstants.Notification.ThemeColor.Error,
CloseAfter = 30000,
Closable = true
But I will not see the notification on screen.
It doesn't matter if this is somewhere in the code or in the
protected override async Task OnAfterRenderAsync(bool firstRender)
protected override void OnInitialized()
