The app (and the website) do require an internet connection to work. It's expected behaviour that any changes you make while offline will not be saved. It sounds like it would be a good idea to have a notification as you describe. If you'd like to make a feature request for this, from the website's 'Help' menu, choose "Request a Feature". That will take you to a Trello card with some simple instructions for making your request. You will need to have a Trello account to do this. Unfortunately this forum isn't a good place for feature requests because they get lost amongst the other questions and requests for help.
