Please make sure each iPad has its unique register profile, rather than used on multiple devices.  2. Please allow at least 30 seconds for the tables to sync to all registers before making any changes to the order on another iPad. 3. Please allow at least 30 seconds for iPads to sync when using the same staff passcode between multiple registers. We recommend using a unique passcode per register as items are linked to a staff code when added to the order. 4. Stay in the POS app at all times, as pressing the home button on the iPad to come out of the app will break the connection and prevent table syncing or receipt/ticket printing. 5. Ensure the iPad is set to “**Never Lock**” (***Settings \> Display & Brightness \> Auto-lock \> Never Lock***) 6. Ensure the iPads are on the same and most up-to-date iOS and POS App versions. 7. Keep the iPads in the service area. Taking an iPad out of its WiFi zone will break the connection. Also, keep the iPads out of any WiFi dead spots. 8. Keep the WiFi private for use with the till system only. This will make sure that the network traffic remains clear. 9. Please ensure that local sync is enabled in the **POS app** (***Cog \> Settings \> General Settings \> Enable Local Sync***). 10. Please make sure that the iPads do not have any other stored WiFi networks and so can only connect to the correct WiFi. 11. Only use one iPad per table to modify the sale. This includes taking orders and printing bills. This will prevent conflicting information from two iPads. - [Front End](https://support.thegoodtill.com/front-end?hsLang=en#main-content) - [Download And Login](https://support.thegoodtill.com/front-end?hsLang=en#download-and-login) -
