Yes, certain nodes aren’t compatible with certain channels purely because the channel doesn’t support the UI.
Eg: Date picker UI won’t be present on FBM or Whatsapp as they would need to have the UI to support it.
However, we do recommend splitting the question of date and month. Alternatively, you can ask the user to enter start and end date in a specific format DD-MM-YYYY and then set the date from your end.
We’re working on improving the omni-channel experience to handle these nodes across all channels.
