How to clear the Savant cache on the iOS TrueControl app 

Clear the cache on the iOS device by tapping on Settings, Systems, Settings and then Clear Cache. (NOTE: This will clear local data from the device, including user-modified favorites.) Then reconnect to the system to see if the buttons show up. 

 On the new Savant app the button is "Clear Systems."
