Overview
This article will walk you through fixing the error encountered when using myPCT and the newest Edge update.
Instructions
Step 1.
In an open Edge browser, click More (the three dots) in the top right, go to help, and click on 'About Edge.'

Step 2.
Make sure Edge is up to date.
If it is not, it should start updating automatically when you reach this page. Once the update is done re-launch chrome.
Step 3.
In the address bar go to the site 'edge://flags.' This should bring up a settings page.

Step 4.
In the search bar at the top of the page search for 'same site'
This should bring up two settings.

Step 5.
Set both "SameSite by default cookies" and "Cookies without SameSite must be secure" to "Disabled."

Step 6.
In the bottom right of Edge should be a 'Relaunch' button, click that to save the changed settings.
The error on the portal page should be fixed.
