When you are trying to update your Aptsys Jade App, you will have to make sure that your main terminal & all existing sub-POS terminals are running on the same version.
Checking App version on POS/Sub-POS
1. Open the Aptsys Jade App
2. Tap through the splash screen
3. Double tap on the right hand side of the screen, where "v.xx" will be shown.
4. Once you have double tapped on that, you should see a pop-up that prompts you of the date and version number. This will represent "As of (date), your app version is (version number)".
