Order Tracking Number Not Updated on real time

I have created a custom page in Shopify and on that page I am showing all the orders of logged-in customers. Now the issue I am facing is that When I update the tracking number of that order from the admin panel then the browser will take a lot of time around 20-30 mins sometimes an hour after that the tracking number is updated on that page. It is working fine when the tracking number is updated by an external app. I am getting data from the customer object.

{% if customer %}
                  {% paginate customer.orders by 250 %}

It’s an issue with the browser. If I turn off the browser and start it again then everything works fine.
