Purge Cache in Power App Portals

This post will be updated to link to a future post that outlines all the different Power App Portals areas. If you have spent more than a few minutes in Portals, you will quickly notice that there is no single place to make updates or change settings.

How do you purge the cache for a portal?
Navigate to the Power Platform admin center
https://admin.powerplatform.microsoft.com/
Click on Environments and select your environment
Select the portal, then click Purge Cache in the ribbon
