Third-party cookies or pop-up blocker errors when accessing Power Automate embedded experiences

This article helps fix common configuration problems that prevent Power Automate from starting in embedded experiences within other apps or websites.

Symptoms

When you access embedded instances of Power Automate, like within SharePoint, Power Apps, or through custom SDK integrations, you might receive a blank screen or have a screen that stays on the spinner.

Cause

These issues occur because third-party cookies are blocked in the web browser.

Resolution

Power Automate stores some data, such as user identity and preferences locally, using your browser's capabilities. Problems occur if the browser blocks the storage of such local data or third-party cookies set by Power Automate.

To solve the issues, go to the settings of the browser you're using, enable the third-party cookies, and make sure that the related sites aren't blocked for cookies.
