C-Trax downloads data to the app to support offline cash transactions and ensure speed. An unfortunate side effect of this is you must tell your app when to download any changes made in Admin.
There are two ways to do this.
Force Close C-Trax Serv
Double tap the home button on your iPad
Swipe C-Trax Serv off your screen
Relaunch C-Trax
Re-initialize POS Data
Open your settings, select other and select re-initialize POS data
