Symphony does not launch in Google Chrome

In Google Chrome version 80 or higher, the SameSite attribute in the cookie is enforced by default. As a result, users accessing Symphony via Google Chrome may receive a 414 Request-URI Too Large error (Figure 1), or Symphony may keep on spinning in an infinite loop when it tries to launch:

Resolve this issue by following the steps below:


1. Navigate to chrome://flags in a Google Chrome window

2. Search for samesite in the search bar (Figure 2):
