In this version we've added a new system variable that gives you access to the network connectivity status.
The IsOnline variable is set with value 'true' when the network connection is available and with a value of 'false' when there is no internet connection. This enables you to create any conditional logic, for example, a condition to disable your submit button if the network is off or even to show some kind of notification icon or error message.
Watch how to use the IsOnline option in the hidden system values
Enjoy!
