Lawson Mingle is loading apps to a blank page

Have you ever had a user in your organization setup correctly with all Lawson and Mingle security roles, yet when they login to Lawson Mingle and select any apps from the waffle tray, they get a blank page upon loading? This is a common thing that can be fixed.

As of writing this, Chrome is the primary support offered for Mingle.

First go to settings in Chrome

Search “Third-Party” in the settings tool bar and select Cookies and other site data

Make sure the Block third-party cookies in Incognito is selected

This should resolve the Lawson apps being blocked and presenting a blank page in Mingle.
