By default, the app will only sync your last 14 day's orders. Sometimes you may need to sync the orders in the past. Therefore, we provide up to 60 days of order history import as well as synchronization.
Steps
From Track123 order admin
Click Sync orders and you will see the period selection
Select the period and wait for a few minutes.
Why some orders are not synced to the app?
Please check if the product needs to be shipped.
If the orders are not required to be shipped, then these orders won't be synced to the app since they are not necessary to be tracked.
