Cybersource CodeIgniter Session Issue

Question

Using Secure acceptance for checkout in CodeIgniter Framework but after payment from https://testsecureacceptance.cybersource.com/payment

Sometimes it returns to the right response 
(Persists the Session and contains the PHPSSID in the set-cookie request headers)

But sometimes it Logs the user out (The PHPSSID is missing in the set-cookie request headers)

How to resolve this unexpected behavior

CodeIgnitor version 3.1.11

Answer 1

Found a solution by adding

$config['cookie_path'] = '/; SameSite=None';

in config.php
