After making a change to a Helper SmartApp in the new Samsung Connect Smartthings App, and clicking Done to return to the Ecobee Suite Manager Helper SmartApps main menu, the only option is "Cancel". It then prompts to "Cancel" or "Discard". Choosing "Discard" is the only way back to the Main menu, and my changes are actually always saved, but this usually concerns me enough to check them.
