: SfChat

This is not an issue on Android and I am running the exact same code

I have a modal which contains an instance of the SfChat control.

To replicate the issue do the following:
- Create page with SfChat control

* Must ShowTimeBreak enabled

- Bind Messages to some arbitrary ObservableCollection<object> (CurrentUser does not influence the outcome and the Observable collection you bind to has to be in a model, e.g. I have a Chat model which wraps all meta data and has a LoadedMessages property which is an ObservableCollection<object>)
- Push the page as a modal
- Send a message / pop the modal

iOS 13.3, tried on iPhone 11 and iPhone 8 and this behaviour is visible only if the property bounded to Messages has some messages in it

Whenever I send a message I get a null reference exception with no trace

Whenever I pop the modal i get the following exception & trace:

{System.NullReferenceException: Object reference not set to an instance of an object
