Troubleshooting synchronization issues between multiple devices

Why aren’t my devices synchronizing?

For your devices to synchronize properly, they must:

• Be connected to the same shop
• Be connected to the internet

Check that the devices are connected to the same shop

To see all devices linked to your shop:

• Go to Settings > Devices. You will find the list of connected devices.
• Adding new devices is available with a Premium subscription.

Why aren’t sales synchronizing?

In some cases, sales do not synchronize because:

• A device is not connected to the internet
• Sales were recorded in offline mode. Without an internet connection, the device cannot send sales to other devices.

How to force synchronization?

To make sure everything is properly synchronized:

• On the device where sales are not recorded online, connect it to a stable internet connection
• Go to Settings and verify that all devices are up to date

• Go to the Dashboard tab and pull the page down → A success notification will appear if synchronization is effective
• Make sure all devices are using the same version of the application. To download the latest version: https://link.tunder.co/share-tunder
