To see updates made in Power Apps Portal, it's crucial to clear the cache regularly, as the portal uses caching for performance optimization. Admins can clear the cache by signing into the Dynamics 365 portal, navigating to a specific URL, and clicking the clear cache button, though this may temporarily degrade performance while data reloads. Clearing the cache ensures that all recent changes are visible on the portal, enhancing efficiency and speed.

1. How to Clear the Cache in the
Power Apps Portal
When you optimize Power Apps portal, you may need to edit pages, assign roles to users, and make
some other required changes. It is necessary to see all the changes you make instantly on the portal. To
do that, you should clear the cache on a timely basis.
When you clear the cache, it helps make sure that all the latest updates to the portal metadata and
DATAVERSE info are visible on the Power Apps portal.
The Power Apps portal uses caching to enhance the potal’s overall performance. This implies that the
portal doesn’t send a direct request back to the Dataverse for individual data updates. This is because if
it sent this request, the performance of the Dynamics 365 portal would be very slow. However, there is a
disadvantage.
If you use an internal app (like Dynamics 365 or custom model-driven) or update via flow or other
integrations to make updates in Dataverse, these changes may not be visible on the Dynamics 365
portal.

2. If you are the admin and are troubleshooting Power Apps cache issues, here are the steps for it.
Steps to Clear Cache while Working with Power Apps Portals
As a portal admin, you can clear the cache on the server-side for the entire portal to reflect changes in
the Dynamics 365 portal in real-time.
Step 1. Sign in to the Dynamics 365 portal as an administrator.

3. [Portal User With Administrator role inD365]
[Log in the portal by Admin user]

4. Step 2. Navigate to the URL as follows: /_services/about.
Step 3. After this, the portal details page will be open. Click on the Clear Cache button to clear the cache.
Note: There is one thing that you need to consider here. Clearing the portal’s server-side cache or
configuration tables’ cache may cause temporary degradation of the performance while data is being
loaded from Dataverse.
Conclusion
By clearing cache, you can get to reflect changes on the Dynamics 365 portal in no time. This helps you
speed up the processes and increase efficiency.
