That just means that your order was indeed shipped out and is in transit as of XX/YY.
The reason why there is no tracking code update after that date shown in last tracking code status is because the order is on the way and typically the tracking code doesn't update before entering the destination country as there are no hard stops in between during which it can update.
Please see below an example from one of the recent shipments showing the behavior as explained:
The next update will typically be once it enters the destination country (USA in the example above), but overall the shipping time should be within typical shipping time frame regardless of tracking code status update.
Typical shipping time for your region from the date of shipping:
USA: Between 5-15 days (10 days on average) from shipping date
Canada: Between 10-20 days (11 days on average) from shipping date
Europe: Between 10-20 days (12 days on average) from shipping date
Australia: Between 10-20 days (12 days on average) from shipping date
All Others: Between 10-30 days from shipping date
